Boot loop MSI A88XM-E35 AMD APU A8-5600K (Aruba HD7560D)

[Bib]

Boot looping since initial 14.04 install. I recently upgraded to 16.04.3 and fell in the same issue as upgrade overwrote my /etc/default/grub without prompting, AFAIR.

WORKAROUND: When using free radeon driver:
nomodeset

or:
radeon.dpm=0

Bib, thank you for reporting this and helping make Ubuntu better.

To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Bib (bybeu)]

Hi Christopher.
Will a live test be enough ?

[Bib (bybeu)]

I can't boot the system: after selecting the live USB as the boot drive, a message displays 1s repetitive ~CRC32~* or something like that. Then I have to type TAB key (nothing on screen drives to this action). Once TAB key was pressed, I select "live" option, then the system reboots in seconds. I also tried "help" but before I can read the whole F2-F10 that keep scrolling up out of the screen at the same rate the ~CRC32~ did, the installer takes some option the reboots on its own. I also tried F4 but nothing helpful happened.

*BTW, I checked MD5SUM iso download : md5sum bionic-desktop-amd64.iso was 064ab6173bc942d3327098f57748182e from today (2018-01-29 08:00)

[penalvch (penalvch)]

Bib:

1) Regarding the error booting Bionic, could you please capture the error message via video recorder (cell phone, etc.)? The provided "repetitive ~CRC32~* or something like that" is not enough information to debug the issue.

2) Regarding the error booting Bionic, is this the same error message received when not using the WORKAROUNDs with your current release?

3) Alternatively, could you please test http://cdimage.ubuntu.com/releases/17.10.1/release/ and advise to the results?

[Bib (bybeu)]

1)Captures attached
2)I'll give a try to this and report.

I'm currently creating another bionic-desktop-amd64 bootable USB stick from the yet installed 16.04.3 instead of the 14.04 one I used.

[Bib (bybeu)]

News : please note that when creating the new stick over the existing one I wasn't prompted to create persistent storage (maybe the disk-creator used the one previously created, I don't know, but a new dummy folder on the desktop in the daily-bionic live once first booted as a check for this question didn't survive next reboot, so I assume the whole key is read only).

So : first boot and following ones, after select a space key hit in the splash screen I now get the semi-graphical menu to select language, keyboard, etc...
First boot I only choose French then Enter : all good to the Ubuntu desktop.
Here I tried to find something special is in /etc/default/grub and don't see anything. System details just show Aruba for video, but repository manager says no proprietary is in use.
Next boots just loop (strange)! Only nomodeset or radeo.dpm=0 allow access to Ubuntu bionic desktop

[penalvch (penalvch)]

Bib:

1) Regarding the error message:
gfxboot.c32: not a COM32R Image boot:

One may type the following and hit enter:
live

This is a known issue from LP#1325801.

2) The video capture unfortunately didn't reveal anything useful. Could you please capture the boot following https://wiki.ubuntu.com/DebuggingKernelBoot ?

[Kai-Heng Feng (kaihengfeng)]

I think you should try latest mainline kernel first. There are lots of radeon fixes since v4.10.

[Bib (bybeu)]

Just tried : bootloop in K4.15 without radeon.dpm=0

I still have to check the advise #10 from Christopher about DebuggingKernel. But I guess I'll fall in another problem : on my system, /tmp is on another Disk/partition than /, so I think I won't be able to get the initramfs.debug file that is asked.

[penalvch (penalvch)]

Bib, could you please attach a video of when removing the boot options while using the latest kernel 4.15.1 (4.15 is slightly older)?

The initramfs section is not relevant at this point given your system is immediately boot looping.

[Bib (bybeu)]

The (bad) Artist, v4.15.1. This is awful, how can you get info from this. I set resolution to highest possible and enabled auto-stabilization.
Don't we have in linux something like the /debug option of windows NT boot.ini that allows to dump boot to a serial port ?

[Bib (bybeu)]

Another shoot. Should I remove the 2 previous ones?

[penalvch (penalvch)]

Bib, the issue you are reporting is an upstream one. Could you please report this to them via https://bugs.freedesktop.org/enter_bug.cgi?product=DRI :
Component: DRM/Radeon

Please post a link to the upstream report here so that it may be tracked.

[Kai-Heng Feng (kaihengfeng)]

Unfortunately, I can't play any video you attached

[Bib (bybeu)]

Kai-Heng, it seems you have a bug. Both videos play fine here with firefox or VLC or Totem.
