This happens to me, lunar, kernel 2.6.0-20, Lenovo Carbon X1 gen 7, Dell
monitor with built-in thunderbolt hub. Seems to happen more likely with
big graphic updates (such as page change in Firefox).
(Monitor/hub works flawlessly with a dell laptop)
It starts with
[ 2713.078178] pcieport :06:
I understand that it's fixed in the mainline quite a while ago, no?
Don't get it why is "verification-needed" now...

I had this happen again about a week ago, though it happens very rarely
now.

Title:
Sound w/SOF driver sporadically fails
Public bug reported:
Now and then, the notebooks stops producing any sound, and program that
try to use sound output freeze for many seconds. There is a repeating
sequence on messages in `dmesg`:
[116525.402057] sof-audio-pci :00:1f.3: error: ipc timed out for 0x8001
size 120
[116525.402
I was encountering this problem before and had to fall back to the
legacy driver (that works but without microphone). Now I was able to
blacklist legacy driver again, and got SOF working, including the
microphone.

I can confirm
Using the kernel package from -proposed makes suspend work normally as
well.

Though I guess that 5.4.0-20 uses the "workaround", and it may be better
to apply the "proper fix" from comment 21
@mapengyu, I've rebuilt e1000e.ko with your patch applied to 5.6.0-rc5
tree, and suspend works normally for me:

I can confirm that suspend works normally with the kernel from comment #16
Thank you!

Title:
suspend only works once on ThinkPad X1
To check the theory from comment #13, I built kernel from mainline at
tag v5.6-rc5. Out of the box, it behaves the same way as all recent
kernels: suspend works only the first time. I could not revert commit
f15bb6d (there were later changes), instead I commented out the calls to
e1000e_s0ix_entry_
JFYI, with the current "proposed" kernel behaviour is the same (problematic):

I do not understand that.
With the current "official" kernel, the problem still exists:

The only kernel that works for me is 5.4.24-050424-generic from

@kaihengfeng, unfortunately that does not work.
I could not find time to do git bisect (each kernel build takes a long time),
but it would not help if I did. I did a "bisect" over the packages in
https://kernel.ubuntu.com/~kernel-ppa/mainline/. The problem is, between the

Could the culprit be enabled "wake on LAN" functionality of e1000e, that
was not enabled in 5.3?

Correction: setting `snd_hda_intel.dmic_detect=0` does make
snd_hda_intel driver work (without microphone, as before).
However SOF driver that worked in eoan (5.3) kernel _with upstream SOF
firmware_ does not work in focal (5.4) kernel. Microphone _did_ work
with SOF.

Sound does not work for me on ThinkPad X1 Carbon 7gen with the same messages in
dmesg.
Specifying 'snd_hda_intel.dmic_detect=0' does not change behaviour on 5.4.0-16,
and if I specify it with 5.4.0-14, it hangs a few seconds after boot. Sound
worked on eoan (kernel 5.3.0-40).
