[Lenovo IdeaCentre A740] Doesn't poweroff on shutdown

[Kevin Brubeck Unhammer]

With my Haswell based Lenovo IdeaCentre A740, if I do "systemctl poweroff" or use any GUI to try to shut down, it gets to the stage of:
[ OK ] Reached target Shutdown
reboot: System halted

but just sits there unresponsive, and does not actually power down.

Similarly, if I try running "fwts -P", the hibernate test seems like it crashes the computer (screen is on but unresponsive), then if I click the power button twice, it resumes from hibernation just fine.

If I try to reboot, it's almost the same, except the display shows weird psychedelic lines and colours, but everything is unresponsive and I have to click (and this time *hold* not just simple click) the power button.

I can reboot fine from GRUB with ctrl+alt+delete. I've kept the Windows partition that came with the computer, that also powers down and reboots fine.

If I click the power button while Ubuntu is started, it powers off immediately.

I originally asked a question at https://askubuntu.com/questions/632591/system-does-not-power-off-on-poweroff-just-halts but I don't think it has an answer since this seems more likely to be a kernel bug.

WORKAROUND: Use kernel parameter:
acpi=noirq

On testing hibernation, the screen first blanked out for half a second, then showed the desktop again, but unresponsive. I clicked the power button, it turned off, then clicked the power button again, and it resumed fine with my terminal open. So hibernation "works" except, like with "systemctl poweroff" it doesn't actually power off.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Kevin Brubeck Unhammer (unhammer)]

No fix upstream :-/

This was a fresh install as of some days ago, these are the only kernels I've tried:

ii linux-image-3.19.0-15-generic 3.19.0-15.15 amd64 Linux kernel image for version 3.19.0 on 64 bit x86 SMP
ii linux-image-3.19.0-18-generic 3.19.0-18.18 amd64 Linux kernel image for version 3.19.0 on 64 bit x86 SMP
ii linux-image-4.1.0-040100rc7-generic 4.1.0-040100rc7.201506080035 amd64 Linux kernel image for version 4.1.0 on 64 bit x86 SMP

[Kevin Brubeck Unhammer (unhammer)]

That BIOS update is for Broadwell systems only, mine's a Haswell (BIOS revision 00KT19AUS).

$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

gives

I have exactly the same issue with an Medion Akoya E1232T, with two minor differences:
1: After halt I have to press the power button long to switch it of physically.
2: After reboot I get a black screen.

Apart from that the behaviour is exactly as described by Kevin. This machine has a Silvermont N2807, Bay Trail graphics and an Insyde Bios, which I flashed to most recent update. I installed Kubuntu 14.04 in EFI mode. As far as I can tell it does not have a legacy mode.

[penalvch (penalvch)]

Kevin Brubeck Unhammer, could you please test the latest mainline kernel (4.1.1) and advise to the results?

[Kevin Brubeck Unhammer (unhammer)]

exists upstream in v.4.1.1 as well :(

[penalvch (penalvch)]

Kevin Brubeck Unhammer, just to confirm, did this issue not occur in a release prior to 15.04?

[Kevin Brubeck Unhammer (unhammer)]

This was a fresh install of 15.04, I haven't tried earlier releases so I don't know.

[Tiedemate (bjoerntiedemann)]

I have created a seperate bug for the Medion Akoya E1232T: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1472274.
Christopher, I have subscribed you.
Thank you!

[Kevin Brubeck Unhammer (unhammer)]

Tried 14.04 Utopic UEFI from an USB drive, it has the same behaviour as the recent kernels.

[Kevin Brubeck Unhammer (unhammer)]

Oh, sorry for the mix-up! The image I used is called ubuntu-14.10-desktop-amd64.iso
So 14.10 Utopic.

[penalvch (penalvch)]

Kevin Brubeck Unhammer, for regression testing purposes, could you please test 14.04.0 (not 14.04.1+) via http://old-releases.ubuntu.com/releases/14.04.0/ and advise to the results?

[Kevin Brubeck Unhammer (unhammer)]

ubuntu-14.04-desktop-amd64.iso also has the same problem

[penalvch (penalvch)]

Kevin Brubeck Unhammer, 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?

[Launchpad Janitor (janitor)]

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Kevin Brubeck Unhammer (unhammer)]

The bug is still present on linux 4.2, but I haven't been able to boot with 4.4, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574178

[penalvch (penalvch)]

Kevin Brubeck Unhammer, are you able to test with this on the latest mainline kernel (4.6-rc5)?

[Kevin Brubeck Unhammer (unhammer)]

Tried 4.6-rc5, can't boot with that either :( – it gives the exact same issue as 4.4

[Kevin Brubeck Unhammer (unhammer)]

4.2.8-wily boots, but has the same no-poweroff-issue.

4.3-wily does not boot (as in bug 1574178)

[Kevin Brubeck Unhammer (unhammer)]

Would it make sense to report this upstream?

[penalvch (penalvch)]

Kevin Brubeck Unhammer, it would, but the root cause for this issue hasn't been identified.

[penalvch (penalvch)]

Kevin Brubeck Unhammer, one thing that may help reveal the root cause here is if you add the following kernel parameter via https://wiki.ubuntu.com/Kernel/KernelBootParameters:
debug=y

then when it's stopped, post a screenshot via camera.

[Ratrop (ratrop)]

Same issue with Haswell based Lenovo IdeaCentre A540 with same bios:

09/30/2014

[Kevin Brubeck Unhammer (unhammer)]

I got a tip from Navin at https://bugzilla.kernel.org/show_bug.cgi?id=118401
to try acpi=noirq and this does not only let me boot kernels>=4.3 (I'm writing this from mainline 4.7!), but also makes it poweroff and restart correctly.

However, it does not resume from suspend (it seems to suspend as it should, but clicking the power button to turn it back on does nothing).

[penalvch (penalvch)]

Kevin Brubeck Unhammer, to clarify, which mainline 4.7 kernel did you test specifically?

[Kevin Brubeck Unhammer (unhammer)]

linux-image-4.7.0-040700rc2-generic_4.7.0-040700rc2.201606051831_amd64.deb
though the 4.4.0-24.43 from regular xenial repos also booted fine with acpi=noirq

[penalvch (penalvch)]

Kevin Brubeck Unhammer, when communicating with upstream developers, they want to see that you are testing the latest release available (now 4.7-rc5).

[Kevin Brubeck Unhammer (unhammer)]

4.7rc5 has same behaviour: does not boot with acpi=noirq, does boot with acpi=noirq.

[Ratrop (ratrop)]

With acpi=noirq I confirm that can boot kernels>=4.3 (I'm writing this from 4.4.0-28-generic) but does not actually power down

[Ratrop (ratrop)]

Also confirm that With acpi=noirq can boot kernel 4.7-rc6 but does not actually power down. Reboot work properly

[Kevin Brubeck Unhammer (unhammer)]

Ratrop, any difference with pci=noacpi?

[Ratrop (ratrop)]

Same with pci=noacpi with kernel 4.4.0-28-generic and 4.4.14-040414-generic. And also wi-fi card not working with pci=noacpi

[Nicolas K (nielks)]

Hello,

Same hardware configuration as Ratrop (Lenovo A540 with same bios revision)
I use kernel 4.4.0.53, with "acpi=noirq", and have the same issue: poweroff hangs at exit screen.

[Kevin Brubeck Unhammer (unhammer)]

Hm, I'm currently using 4.7.0-040700rc5-generic on 16.04 with

$ grep acp /etc/default/grub
GRUB_CMDLINE_LINUX="noprompt persistent acpi=noirq"

and have fully working boot, reboot, poweroff (on the Lenovo A740, not A540).

(For wifi, I use https://github.com/lwfinger/rtl8723au dkms).

nielks, could you try a newer kernel, e.g. 4.7.0-040700rc5-generic ? If the same kernel doesn't work, maybe A540 has a different issue regarding poweroff.

[penalvch (penalvch)]

Nicolas K (nielks), to track your hardware, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

For more on why this is helpful, please see https://wiki.ubuntu.com/ReportingBugs.

[penalvch (penalvch)]

Kevin Brubeck Unhammer, to keep this relevant to upstream, one would want to periodically check for, and test the latest mainline kernel (now 4.9) as it is released.

Could you please advise?

[Nicolas K (nielks)]

Christopher M. Penalver, I just created https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1651294 and subscribed you. see you there :-)

Kevin Brubeck Unhammer, thanks for the tip, I will try rtl8723au.
With r8723au, my wifi interface is working for some time (maybe 10min), then hangs.
Same for you ? Does rtl8723au works fine ?
(that was the next problem on my list ! )

[Kevin Brubeck Unhammer (unhammer)]

I'll check with 4.9, yeah.

(And yes, rtl8723au ("modprobe 8723au") works fine, while the built-in r8723au I blacklist since it drops out too much. I don't know if that should be a separate bug or if there's a good reason for not having rtl8723au by default; lwfinger seems to be a kernel driver maintainer anyway)

[penalvch (penalvch)]

Kevin Brubeck Unhammer, regarding the WiFi, yes this is a separate issue not scoped to this report.
