Bug#949020: linux-image-5.5.0-rc5-amd64: Poweroff/suspend doesn't work in 5.5.0-rc5

Lennert Van Alboom-2
Package: src:linux
Version: 5.5~rc5-1~exp1
Severity: normal

Neither shutdown nor suspend works in this kernel version. Systemd seems
to indicate it is trying at least, but the system hangs either right
before shutdown (clean situation, requiring a poweroff with the power
button) or before sleep (hung system, can't do anything except also hard
powering off and rebooting later).

Syslog from a suspend action:

Jan 16 06:43:53 Nesbitt NetworkManager[749]: <info>  [1579153433.6342] manager: sleep: sleep requested (sleeping: no  enabled: yes)

I have the same problem with 5.5.13-2 on a Lenovo Thinkpad T460p, with
4.19 from buster there is no such problem. I didn't debug any further
yet.

I just reconfirmed: linux-image-4.19.0-8-amd64 4.19.98-1 doesn't suffer
from this problem, but linux-image-5.6.0-trunk-amd64-unsigned
5.6.4-1~exp1 has the same problem.

On thing I noticed: When I send my Laptop in suspend, the power LED
starts blinking slowly (as it does with 4.19), but the FnLk LED stays on
which on 4.19 goes off shortly after suspend is reached. So I think the
problem is in the going to sleep step, not only when (not) waking up.

Best regards
Uwe

I started bisecting (but didn't complete yet, the weather is too good to
sit inside :-). Currently I see

        bad: 5.2.17-1+b1
        good: 5.2.6-1

So this is either a regression (also) in stable or something
Debian-specific (or I did something wrong).

I checked the remaining versions in between the two above and the bisect
result is that

        5.2.7-1 is the last good; and
        5.2.9-1 is the first bad

kernel image. The relevant change between these two is:

          * [x86] iommu: Enable INTEL_IOMMU_DEFAULT_ON (Closes: #934309)

. At least 5.2.7-1 shows the problematic behaviour when I add
"intel_iommu=on" on the kernel command line. I suspect I can boot newer
kernels with "intel_iommu=off", but didn't try that yet.

@Lennert: I assume you can still reproduce the problem. Do you care to
test with intel_iommu=off and report about the result? Just to make sure
you and I see the same problems?

Best regards

I'm afraid I can't test this anymore - due to serious i915 issues I've been building and running my own kernel packages. Currently running 5.7.0-rc1 (which is still just as broken as 5.4, 5.5 and 5.6... sigh) . I haven't seen the poweroff/suspend problem in a good while.

So the newer kernels don't fix your problems? In my experience the i915
guys are quite responsive and willing to help if you run a recent
kernel.

Do you have INTEL_IOMMU and INTEL_IOMMU_DEFAULT_ON included in your
custom kernel? (If only the former: Do you suffer from the reported
problem when you add intel_iommu=on to the kernel command line?)

Best regards
Uwe

They don't. I've reported a bug for it a good while back:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949021

https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/issues/183
https://gitlab.freedesktop.org/mesa/mesa/-/issues/2352

Awfully quiet there. There seem to be multiple similar bugs around; so far the only response I got upstream was the bug being closed and moved to "mesa" (which I don't really get either). Debian bug didn't get any acknowledgement or comment.

I started with the stock Debian 5.5-rc config, and just did make oldconfig from there on (don't like to stray too far from the official packages). So the option should be identical to the Debian kernels.

$ grep INTEL_IOMMU Build/kernel/linux-5.7-rc1/.config
CONFIG_INTEL_IOMMU=y
CONFIG_INTEL_IOMMU_SVM=y
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
CONFIG_INTEL_IOMMU_FLOPPY_WA=y
CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON=y


I don't reboot often, but I'll very likely run into the i915 hang above again soon, so I'll try the intel_iommu=on then.

Verified: my 5.7.0-rc1 system with intel_iommu=on can suspend/resume without issues.

I brought this problem to the attention of the x86 guys; see above URL
for the conversation.

Up to now no breaking insights.

@Lennert: Did you change your BIOS settings since the problem occured to
you? Lenny Szubowicz hinted it might be related to the TPM chip and
indeed switching it in the BIOS settings from 2.0 to 1.2 mode makes the
problem go away for me.

Bug#949020: linux-image-5.6.0-2-amd64: Lenovo poweroff/suspend failure

Bjørn Mork
In reply to this post by Lennert Van Alboom-2
Package: src:linux
Followup-For: Bug #949020

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Just confirming that this issue is still present, causing a terrible
user experience when upgrading from Buster to Bullseye on a Lenovo
laptop. Verified on a 4th Gen Thinkpad X1 Carbon.

Setting intel_iommu=off is confirmed as workaround.

I understand from the upstream discussion that this is mostly a
Lenovo firmware issue.  But I still believe something needs to be
done in Debian to avoid every Lenovo user having to discover this
bug report and implement the workaround manually.  After first
experiencing a complete system failure when trying to suspend
the system.  A feature which worked without a flaw on Debian
Buster.
