Ubuntu 14.04 suddenly reboots when booting from Live USB AMD A8 6600k

I have a custom built AMD System with the following hardware currently running on Linux Mint 16 :

AMD A8 6600k with Integrated graphics | MSI-FM2-A55M-E33 Motherboard | Kingston Hyperx Blu 4GB RAM | Corsair VS450 PSU

Today when I tried to install 14.04 amd64 iso using a bootable USB, then the system rebooted. Any further attempts in installing it resulted in the same bug. As soon as I open the "Ubuntu installer" application and click "Continue" button then the system restarts after 2-3 seconds.

I asked the same on AskUbuntu and some more guys reported the same problem with AMD APU, so I believe it to be a genuine bug and not just with me.

The BIOS version is the latest one downloaded from MSI official website which is version 11.5.

Also an Interesting thing is that this bug is common with the latest iso of Arch Linux too, but when booting older distros like Linux Mint 16 from USB, then everything works like it should, so it might have something to do with the newer 3.13 Kernel version.

I am not an expert, but I can surely tell that only the newer distros are affected by this bug as reported by some other guys at AskUbuntu and the fact that Arch which is running the newer Kernel is having the same bug, so it probably has something to do with the newer Kernel, but I could be wrong.

This bug is not letting me install Ubuntu 14.04 on my hardware and it is affecting a few more users too. Here is the AskUbuntu thread : http://askubuntu.com/questions/449391/unable-to-install-ubuntu-14-04-pc-restarts-after-i-click-continue-button-in

I hope this gets fixed soon or with the 14.04.1 upcoming July release.

[Sangeet Khatri (sangeet-khatri)]

@crichton The problem is that there is no package I know of that is causing this bug. Whenever I boot 14.04 from USB, the Ubuntu itself is very unstable and reloads while doing some little things like changing the settings or Opening the Hard Disk folder and worst of all, while installing. So, this is a bug not related to a specific package but it is affecting the whole Ubuntu 14.04 release.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Marc Panlilio (jugglerobot-deactivatedaccount)]

Not trying to be an expert here, but this might help others too so here I am. So I am having the same issues here as well trying to install Ubuntu 14.04 LTS on a Live USB. I am using an "Trinity" APU model here. I have used a kernel commandline "noacpi" in GRUB edit menu, just get these logs. Here's my hardware, just incase if it's needed:

AMD A6-5400k Trinity APU | AMD Radeon HD 7540D "AMD ARUBA" | MSI FM2-A55M-E33 Motherboard | Kingston DDR3 1333 RAM | Corsair VS450 PSU

[Ader (rasmusrim)]

I am now trying to install Ubuntu on a manually created partition. I am running gparted from the USB, and try to create a new partition. That is not possible, since there are already four primary partitions. I assume that the automatic install (install inside windows 7) also needs to create a partition. Could this be the problem?

[Eric Harris-Braun (zippy)]

I am seeing the same problem using an MSI A88XI motherboard; an AMD A6 5400K processor; patriot DDR3 RAM.

[Sangeet Khatri (sangeet-khatri)]

Looks like this bug primarily affects MSI Motherboards or AMD APUs in general. Some guys from AskUbuntu reported the same.

[Muhfi Asbin Sagala (muhfiasbin)]

This problem affects me too. I am trying to install Ubuntu 14.04 both from USB or DVD and get this experience.

Processor AMD A8-5600K
Motherboard MSI FM2-A75MA-P33
Corsair Vengeance DDR3 8GB (2x4GB) Dual Channel

[Sangeet Khatri (sangeet-khatri)]

It would be safe to assume that this bug primarily affects MSI boards. We all should watch out for a BIOS update from MSI.

[gerst (gerst)]

I got the same problem, running MSI motherboard with AMD A8-5600K CPU

[gerst (gerst)]

I`ve forgot to add It was a 64bit edition of Ubuntu 14.04. Previously I was running Manjaro 64-bit with no problem.

[Sangeet Khatri (sangeet-khatri)]

Something in the 3.13 Kernel and older is affecting MSI boards, because Arch is also a no go. I haven't tested things other than Ubuntu and Arch though. The bug lies in the very Kernel (probably).

[Muhfi Asbin Sagala (muhfiasbin)]

I have tried another workaround, but this cause a lot of pain for me.
First, I install Ubuntu 13.10 Saucy Salamander then upgrade it to Ubuntu 14.04 Trusty Tahr. Upgrade process was succes. But, when my computer boot, it restart after shown Login Screen and it happen over and over.

I tried accessing root console from recovery mode, then run command apt-get update && apt-get upgrade. It's update the kernel from 3.13.0.24.28 to 3.13.0.24.29. I reboot and my computer still restart over and over.

I tried install fglrx-updates from recovery mode and reboot again. Now, my computer is fine.

[gerst (gerst)]

I`ve managed somehow to install 14.04, it didn`t restart itself...I`ve tried about 10 times when finally suceeded :) But after when I reach the login screen it restarts... :(

[Sangeet Khatri (sangeet-khatri)]

Issues like these should be fixed soon in a LTS release since so many people use AMD APUs these days because they are so cheap and are perfect for Linux boxes as they have inbuilt graphics and very good connectivity for A75 and higher chipset boards.

[Marc Panlilio (jugglerobot-deactivatedaccount)]

Well I also have my own workaround, but seems complicated. I finally installed Ubuntu 14.04 successfully using this, but the problem is my PC won't shutdown if this is applied in the kernel boot parameters. I've added "acpi=off" on the GRUB configurations, which is located in /etc/default/grub

Also, when I click Shutdown in the right upper gears button, it will reboot instead! Not shutdown! Lol what the he**!

I can confirm, this is a problem in the kernel. Something with the "ACPI" drivers, or may be not.. Again, I'm not trying to BE an expert here. I also tried using the latest trusty 3.14.0 kernel from Ubuntu Kernel PPA's:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/

No luck! :(

[gerst (gerst)]

I didn`t expect such a big bug in LTS...

[Алхимов Александр (aleks-nl5)]

This problem affects me too. I am trying to install Ubuntu 14.04 from USB and PC reboot's after 3-5 min work in live mode.

Processor AMD A4-4000
Motherboard MSI FM2-A75IA-E53
Kingstone DDR3 2GB

[Incze GASPAR (inczegaspar)]

Bug appears on MSI A88XM-E35 + AMD A8-5600K 3.60GHz FM2 BOX, older kernel works OK.

[gerst (gerst)]

14.04 LTS fail...

[Sangeet Khatri (sangeet-khatri)]

@gerst : 14.04 is not a fail by any means, it is just that currently we are unable to run it on our hardware, with a bug fix or perhaps a BIOS update from MSI, things would be alright again.

Meanwhile 14.04 flies on my Intel's Core2Duo laptop. It is pretty awesome.

[gerst (gerst)]

We are talking about LTS release, and this is a pretty nasty bug, making 14.04 useless for many people.

[gerst (gerst)]

These kind of a errors should be fixed fast, not waiting for weeks...

[Per Engström (per-10823-n)]

One of my PC:s is also affected by this bug!

I have a PC with MSI FM2-A55-E33 motherboard and a AMD A4-5300 APU, 4GB RAM.

Ubuntu 14.04 LTS 64-bit does not work on it either. Boot from Live-DVD fails after half boot-up, screen goes black and after approx 5-8 seconds the computer reboots and locks at EFI GRUB.

Any other recent Ubuntu works on this computer, the exception being U 14.04 LTS 64-bit. If I do a fresh U13.10 install it all works great, but if I do a dist upgrade from that U 13.10 to U 14.04 LTS the installation process works fine, but after the finalizing reboot it crashes seconds after the 14.04 Login screen appear, reboots and goes into locked mode at EFI GRUB. Hard Power Off is requiered.

I have reverted to U 13.10 on this machine for the time being while a fix is developed by some of you Ubuntu wizards..

/Per in Sweden

ps. I have another PC with a MSI motherboard, FM2-A85XA-G65, a AMD A10-6800K APU and 8GB RAM. But it seems to be working, did a dist upgrade from U 13.10 to U 14.04 LTS and it has not crashed yet after a couple of days. It starts, reboots and functions apparantly as normal.

[Blake (getechdirect)]

I have an ASROCK FM2A88X-ITX+ with a A10-5800k and this has not affected me although I installed the beta 2 from usb, not sure if this helps narrow it down. Yall should try to install one of the betas and see if you still get the same issue, if not compare kernel changes.

[jonathan green (jonathangreen)]

This bug seems to be causing me problems. Updated from 13.10 to 14.04 and now my PC reboots every time I try to boot into Ubuntu. I am running ubuntu server. It seems to pop up randomly, sometimes I only get part way through the boot sequence, and sometimes I even get to the login prompt, but then it always reboots.

It reboots if I choose Kernel 3.13, but not if I choose kernel 3.11 or 3.13 recovery mode. My system configuration:
AMD A8-5500
MSI A88XM-E35

[Sangeet Khatri (sangeet-khatri)]

@Blake : Well.. it is interesting to know that it is not affecting Asrock boards. I doubt that the problem is limited to MSI boards. Unable to install Arch as well which has 3.14 Kernel.

[jonathan green (jonathangreen)]

FYI: I was able to fix this by passing radeon.dpm = 0 to the kernel.

[Sangeet Khatri (sangeet-khatri)]

But the APU graphics are of the 7xxx and 8xxx series. Not 6xxx.

They probably are based on same architecture. Maybe that's why. But the title of that bug should be renamed to "Kernel 3.13 still broken on Radeon HD based desktops and laptops." and removing the 6xxx because they are not the only one affected.

[penalvch (penalvch)]

Sangeet Khatri, could you please boot into a live environment of a release prior to Trusty via http://releases.ubuntu.com/ and advise if this is reproducible?

[Алхимов Александр (aleks-nl5)]

I think I found a solution of this problem - when boot from USB or DVD you must edit boot options & add this:
radeon.dpm=0
Now I can not install the produce, but by the end of the day I think I'll check.

[Sangeet Khatri (sangeet-khatri)]

@Christopher M. Penalver : I am currently running Linux Mint 16 which as we all know is based on 13.10 release of Ubuntu, so it works fine with the 13.10 or say Mint 16. But the problem lies thus far with 14.04 only. As I have stated earlier, I tried to install Arch as a quick alternative, but that wasn't possible either as it was affected by the same rebooting bug.

I am no expert but I am a geek and can work his way around Linux at times with a reasonable amount of guidance, so please guide me on how could I help.

By the way, looks like my Hard Disk is about to fail so installing distros is not really an option at this point of time. Will soon move to SSD though.

[cb (news-v)]

Same Problem here. I moved Kubuntu 12.04 from old PC to this new PC, runs without problem but needed to upgrade to 12.10 because of a softwareproblem. 12.10 also runs without problems.
Because upgrade to 13.10 did not work I installed 14.04 new from USB, install reboots every few seconds, no matter if I press any button, try to install or just wait, a few seconds after boot it reboots.

Adding radeon.dpm=0 to boot options solved installer. After install kubuntu reboots again after a few seconds. Adding radeon.dpm=0 to grub-boot-line starts ok. Now added radeon.dpm=0 to grub-conf

Hardware:
MSI A78M-E35 (MS-7721) and AMD A4-4020 APU with Radeon(tm) HD Graphics

Also addes dmesg.1.gz from first boot without radeon.dpm=0

Hope this helps somehow, have PC only till tomorrow, it's from my neighbour

[Matt (mdinger-bugzilla)]

It seems that Ubuntu daily is on kernel 3.16 now so (not certain though). It would be a good test to try installing one of the daily live CD's to see if they still reboot automatically because it's supposed to be fixed with 3.16. Also run `uname -a` in the terminal to check which kernel is being used.

These are daily builds and not meant for production so take care when using them. I found the daily live ISOs linked from http://www.phoronix.com/scan.php?page=news_item&px=MTc2NzI

http://cdimage.ubuntu.com/daily-live/current/

[panther44 (billconiston)]

My issues were fixed by changing the graphics driver under the additional drivers programme to: fglrx
(not updates - that still didn't work for me)

Did not require a reboot to start using and no problems since switching - quick fix for anyone else having the same issues,

[Ader (rasmusrim)]

Hi!
I just tried to upgrade the kernel on my live USB to 3.16. I then rebooted, but I got an intramfs error "Unable to find a medium containing a live file system". How to get past that problem?

[Ader (rasmusrim)]

Clarification: I did this to test if the rebooting problem persists.

[Ader (rasmusrim)]

I just downloaded the latest build of Saucy Salamander to test that version, and the exact same problem occurs there. So this might actually be an older issue.

I have an AMD A8-6600K/MSI G71 FM2 Board. I was getting the reboot loop when installing 14.04 LTS. I used a workaround for this problem. I will explain below in noob terms.
1. install ubuntu. Keep your mouse moving the whole time and you will get through the install. It's tough but you can do it.
2. Once ubuntu is installed, reboot and press F6 during the motherboard screen to bring up ubuntu boot options
3. boot with low graphics and networking.
4. in low graphics mode, open firefox and download the appropriate graphics drivers from AMD for your PC. Install them and reboot back into low graphics mode with networking
5. open terminal and type: "sudo gedit /etc/default/grub" and Look for this text: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
6. Edit this section of code to read as follows: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic radeon.dpm=0"
7. save changes
8. you should now be able to boot in normal graphics mode.

This workaround took me a while to figure out as I'm newer to ubuntu as an operating system, but it has been stable running constantly at full 1080p graphics for four days now without a single crash or error. Hopefully this works for more than just my system.

[Phillip (phil-acomposer)]

whoops sorry my motherboard is an MSI A78M-E35 FM2/2+ board

[Phillip (phil-acomposer)]

And when I say "low graphics mode" I mean "Ubuntu, with Linux 3.13.0-xx-generic (Recovery Mode)" and then on the next menu with the pink background choose the "network -- Enable networking" option. It should boot into 1024x768 and it shouldn't enter the reboot loop.

FIXED restarting problems - I think it was a graphics driver Isssue

CPU: AMD APU A86500 3.5ghz
MOBO: MSI A78M-E35
2x4gb DDR3 RAM HyperX blu 1866mhz

NEW SSHD
SSHD Seagate Hybrid drive 1TB
O/S : Dual boot Windows 7 home premium 64 bit, Ubuntu 14.04 64bit

Hi there, i am a casual user of Ubuntu since 2010 with dual boot of Windows in almost all of my systems. I have used Ubuntu 10.04, 12.04, and now 14.04. I am a newbie in techinical terms, so please excuse the lack of clarity.

Initially i had problems installing Ubuntu 14.04 on the above new built in May 2014 alongside windows 7, both live cd and usb would load to install screen and restart constantly. After a few installation trials i gave up. however i successfully installed Ubuntu 12.04 64bit on the SSD and ran it for months no major issues, and my windows 7 boted fine on the normal hdd Today i wanted to upgrade to 14.04 as i migrated both my OS to my new SSHD Seagate 1TB, my SSD started to fail and i sent it back to Muskin, good after sales service, still waiting for replacement. Had to do boot repair for the old dual boot though, worked fine after that.

It installed fine after a couple of installation trials when it would just restart automatically. Then during the post installation things to do it kept restarting numerous times. So I restarted on safe mode Linux 3.13.0-xx-generic (Recovery Mode), then booted with normal mode, when to additional drivers, unselected 'Using X.org X AMD/ATI display driver wrapper from xerver-xorg-video-ati (open source, tested)', then selected the last option at the bottom 'Using Video driver for the AMD graphics accelarators from fglrx-updates (proprietary)', rebooted and voila, problem fixed so far. I have been using it now for four hours and no restarting at all, cannot speak for longer term, i will post back daily to confirm or correct.

Good luck...

[asheeq subratty (asheeqsubratty)]

ps, no issues with my Windows 7, i use my Asus discrete graphics card as Dual graphics enabled with my APU, so the DVI cable is connected to the MOBO and not the GPU, dunno if this has any significance, jsut thought to mention that.

good luck, and sorry if this isn't the same problem, i couldn't read all the comments, please feel free to advise...

[Steffen Eibicht (steffeneibicht-deactivatedaccount)]

this Bug also affects a customers machine, equipped with a MSI A78M-E45 mainboard with an AMD A4-4000 APU.

This Bug is not in Ubuntu Precise with the 3.2 Kernel. So I first installed Ubuntu 12.04, installed the fglrx-driver via Jockey and then upgraded to Trusty. Up to now, the system runs without random reboot.

Conclusion:

1. the bug occurs in Kernel 3.13 and the free radeon driver

2. the bug does obviously not occur in Kernel 3.13 if fglrx is installed

3. the bug does not occur in Kernel 3.2 with the free radeon driver

4. the bug does not occur in Kernel 3.2 with fglrx installed

Have you talked to MSI and AMD about this issue? Is there any activity going on regarding this ridiculous Bug? Will it ever be fixed or will it survive a whole LTS-cycle and maybe another one (because in Kernel 3.16 it reportedly also occurs)?

Is there anything, we as users can provide to help you fixing this bug? Logfiles? What can we do to help?

[Matt (mdinger-bugzilla)]

Correction: I don't know where you heard but this should be fixed in 3.16. If you are referring to comment #94, he has a different issue. That isn't this bug.

My system similar to those mentioned here:
MB: A55M-E33
cpu: AMD A4 6300
ram: HyperX DDR3 1866 2x4GB

I really didn't have much trouble installing Linux Mint 17 from USB stick. However after install is when the rebooting started. I concur with most of what Rick Robinson said in comment #75. My solution as well was the fglrx-updates driver. However one of the first things I will always do on a new build is to install Google Chrome. I noticed that as long as I had Chrome running there were no reboots. As soon as I would close Chrome, the machine would reboot as if on queue. Possibly the same with the default browser in Mint, Firefox. I don't know that for sure because I only kept it running long enough to download/install Chrome.

I thought maybe that would be true as long as some application was running. I tried running LibreOffice Writer in the background, but it had no effect.

    When booting the .iso image and the keyboard icon appeared at bottom of screen, I pressed any key to enter the options menu. Selected F6 - other options and then selected acpi=off. The .iso then booted without rebooting itself before it got to the desktop, and installed OK. After 14.04 amd64 was installed, the fact that acpi was set to acpi=off in the grub.cfg file was keeping my computer from shutting down properly, so I set it back to acpi=on in the grub.cfg file. Then my shutdown worked properly.

I was having the endless reboot problem with my USB memory stick installing Ubuntu 14.04.
I forget how I built my bootable USB stick, but I just burned the .ISO to a DVD and booted with that. Problem solved.

So I think it's the certain tool people are using to make their USB sticks from the .ISO that's the culprit here.
Maybe there's a common denominator here?

I now tried booting from a DVD without luck. I have also tried acpi=off with no luck. I even tried that hard-to-believe trick with the mouse with no luck. Any chance this bug is fixed any time soon? Is there anything more I can do to help?

Ader, it would help immensely if you filed a new report with a working prior release via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

If for whatever reason there is no prior release, please use as a last resort https://bugs.launchpad.net/ubuntu/+source/linux/+filebug .

Now I tried with radeon.dpm=0 and when the installer rebooted, it gave me the Ubuntu logo with the text "Remove media and press [ENTER]" or something like that. Could it be that the installer thinks that it is actually done with the installation when it has in fact done nothing? I will now install Precise and upgrade to Utopic. Hope that works!

[Ader (rasmusrim)]

Precise did not work either. What on earth can I do to install Ubuntu?

A bit late in the day, but the 14.04LTS install fails on my system too, except if I edit the boot line at CD start up, adding "acpi=off". Then it starts sweet as a nut. Oh my system is a AMD A8 6600k with Integrated graphics | MSI-FM2-A55M-E33 Motherboard

I will add comments on system usability when the install finishes

Same issue with a MSI A88XME35 with latest BIOS (V30.6) in Ubuntu 16.04.3 LTS kernel 4.4.0-112-generic #135-Ubuntu.

Only nomodeset with free driver, or radeon.dpm=0 with proprietary driver prevent boot loop

[penalvch (penalvch)]

Bib (bybeu), it will help immensely if you use the computer the problem is reproducible with, and provide necessary debugging logs by filing a new report with Ubuntu via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

Hi Christopher. Done as you asked.
Have a good day
