Package: linux-image-amd64
Version: 5.6.14-1


Starting with Linux kernel package linux-image-5.6.0-1-amd64 (5.6.7-1) I
get the following error message that is repeating every few seconds:

kernel: [drm:i915_gem_gtt_finish_pages [i915]] *ERROR* Failed to wait
for idle; VT'd may hang.


Affected is at least linux-image-5.6.0-1-amd64 (5.6.7-1) and
linux-image-5.6.0-2-amd64 (5.6.14-1).

The error message does not appear with linux-image-5.4.0-4-amd64
(5.4.19-1).

Hardware is a Lenovo T410 with integrated Intel graphics controller.

This also affects 5.5.0-rc5-amd64.

(https://snapshot.debian.org/archive/debian/20200106T211159Z/pool/main/l/linux/)

The kernel boot option "intel_iommu=igfx_off" prevents the error message.

Bug still present, affects for-example X201-Tablet, similar
hardware to T410 with Intel Graphics variant.


Affects at least debian kernels:-

5.6.0-2-amd64 5.6.14-2
5.7.0-2-amd64 5.7.10-1
5.7.0-3-amd64 5.7.17-1

Hi,
Please do test as well the yesterday uploaded 5.8.7-1 but I suspect
the bug is still present there.

To isolate the issue it might be worth trying to bisect were the issue
is introduced and ideally then reported upstream. Some hints are in
https://wiki.debian.org/DebianKernelReportingBugs#Identifying_when_the_bug_was_introduced

In particular if you found the introducing Debian revision, then do
check the respective upstream stable versions, and then try to bisect
to find the introducing commit.

See https://wiki.debian.org/DebianKernel/GitBisect

Hope this helps,

Regards,
Salvatore

Yes, indeed.

Confirmed between 5.4.19-1 and 5.5.13-1.
"You can find older versions of the kernel in various locations,
including http://snapshot.debian.org."


Where else are these "various locations" !?!? Can they be linked
onto above wiki page? In this case some earlier 5.5's would be
clearly useful test-cases.


Another point that I'd like to see on above page, is -- clear
information on where kernel bugs *should* be filed or *are*
filed with explanation. I.e. src:linux linux-image-amd64
linux-image-VERSION-amd64 and so-on and so-forth!.


Another point that I'd like to see on above page, is clear
information what to do to search for existing kernel bugs,
as "reportbug kernel" would NOT find 962003 for me, this
is related to the above confusion really.

Hi. I just installed Debian bullseye daily today (linux-image-amd64
version 5.10.40-1), and ran into this problem on a Lenovo X201. The
message repeats every other second or so. I don't notice any other
problem except for the repeated messages, fortunately.

I have tried installing the non-free intel iucode and 915 firmware
packages (intel-microcode and firmware-misc-nonfree), but they don't
appear to make a difference.

It seems to have been almost five months since the last report on this. I see this right now on a fully updated Debian 11 on a Thinkpad X201s.

The kernel is 5.10.0-9-amd64 #1 SMP Debian 5.10.70-1 (2021-09-30) x86_64 GNU/Linux.

I put "*ERROR* Failed to wait for idle; VT'd may hang" into a search engine
and found the following:

Second result was https://bugs.archlinux.org/task/65362 which said:
"The change to CONFIG_INTEL_IOMMU_DEFAULT_ON=yes on 5.5.1.arch1-1 causes
random system freezes" and a possible workaround is:
"Adding intel_iommu=off or intel_iommu=igfx_off seem to solve the issue" (seems
more like hiding to me though) and mentioned a potential upstream bug:

https://bugzilla.kernel.org/show_bug.cgi?id=197029
I didn't read them all, but seems various people are affected.
Comment 21, dd 2020-02-03 by Lu Baolu, mentioned the commit that seems to have
caused it:
commit 422eac3f7deae34dbaffd08e03e27f37a5394a56
Author: Jarkko Sakkinen <jarkko....@linux.intel.com>
Date: Tue Apr 19 12:54:18 2016 +0300

tpm_crb: fix mapping of the buffers

Comment 30 is an attempt at a revert of 422eac3f7, but seems not to be the fix.
That bug report ends/stalls (at msg #31) at the point where the request is
made to forward it to linux-integrity ML, which results in https://
lore.kernel.org/linux-integrity/06299499-45d0-23e7...@gmail.com/

To which the single response by Jarkko is:
"This a bit out of my scope albeit concerns TPM."
And IOMMU list was CC-ed

https://lists.linuxfoundation.org/pipermail/iommu/2020-September/
thread.html#48894 did not receive a reply ...

Searching for "intel_iommu=on breaks resume from suspend site:https://
lists.linuxfoundation.org/pipermail/iommu/" oddly enough doesn't return the
mail from September 2020 ...

There is a Debian patch related to IOMMU, but I'm highly doubtful it is
relevant to the cause of this issue as many OS's have come by in my searches.
debian/patches/features/x86/intel-iommu-add-kconfig-option-to-exclude-igpu-by-
default.patch as a fix for https://bugs.debian.org/935270

Putting "intel_iommu=on breaks resume from suspend" in a search engine gave
https://lists.linuxfoundation.org/pipermail/iommu/2017-September/024383.html
which indicates this problem has been present since kernel 4.13 and references
the earlier mentioned https://bugzilla.kernel.org/show_bug.cgi?id=197029

It also has this 'interesting' tidbit:
====================================================
> has it worked ever with intel_iommu=on?

Good point. I just tested that by rolling back to 4.12.13-1
and manually activating `intel_iommu=on`. As expected, no,
resume is similarly broken.

`intel_iommu={on, igfx_on}` probably have been breaking resume
for a long time on my system, I just happened to notice it now
due to being `on` by default.
====================================================

Summary:
It seems to me that quite a few people are affected by this. It also seems to
exist for quite some years and brought to 'light' for many people when IOMMU
got enabled by default. (and virtualization becoming popular?)
https://bugzilla.kernel.org/show_bug.cgi?id=197029 looked the most promising,
but the not unreasonable request to forward it to the IOMMU mailing list seems
to have stalled/ended any progress on it as *in my search* I didn't find any
follow up. But my search may be at fault as it didn't find the 2020-09 msg ...

HTH (a bit),
Diederik

Honorable mention for this one (from 2009-04-10):
http://lkml.iu.edu/hypermail/linux/kernel/0904.1/01834.html
"RE: 2.6.29: can't resume from suspend with DMAR (intel iommu)enabled"
I don't know if it's relevant, but the title and reference to kernel 2.6.29
caught my eye ;) (and DMAR is mentioned in the Debian patch)

I believe, the messages/behaviour was slowing the system or so,
not just giving messages, at least I have seen this on X201T.


The workaround is to boot with kernel parameter intel_iommu=igfx_off

e.g. set in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=igfx_off"
and then re-run sudo update-grub and reboot.

[I tend to remove "quiet splash" but you could of course have
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=igfx_off"


Playing the Git-Bisect game would be helpful if somebody could
find *exactly* where the problem was introduced ......

Thanks -- I discovered this too. I can confirm this workaround
silences the messages. I can't tell if the system remains slowed
down or not, I do get the following messages in the log sometimes, but
it could be that GNOME requires too much resources from this machine.

This seems to be resolved in newer kernel versions.
I'm not able to reproduce this with kernel version 5.14.0-4-amd64 (5.14.16-1).

Great that it is resolved :-)

As many people are affected and the Stable kernel version still seems to
exhibit the problem, I want to ask a question:
Are you willing to help out to narrow down as much as possible which version
introduced the error and in which is was fixed? Wrt the latter, does 5.14.12-1
still show the issue?

Via https://snapshot.debian.org/binary/linux-image-amd64/ you get (easily) get
all the kernel versions that were released.
If we know a (reasonably) small range of kernel versions in which it surfaced
and a small range in which it was fixed, then we could make some educated
guesses as to which commit caused the issue in the first place.

TIA,
Diederik

Just a small update: kernel version 5.13.9-1~exp2 is also not affected by the problem.
