[SOLVED] Laptop keyboard stopped working after suspend in 6.6.13/6.7.0

After upgrade to kernel 6.7.0, I found that my laptop's keyboard stopped working when close the lid and then open it again. I went ahead and downgrade the kernel to 6.6.12 LTS and it worked again.
However, after upgrading to linux-lts 6.6.13 yesterday, the same problem hits again: the keyboard won't work after suspend. I have no choice but to downgrade to 6.6.12 again.
The exact model of laptop I'm using is Dell XPS 9350: https://wiki.archlinux.org/title/Dell_XPS_13_(9350)

Here's my observation:

in kernel 6.6.12, evemu-describe reports 19 devices:

Available devices:
/dev/input/event0:      Lid Switch
/dev/input/event1:      Power Button
/dev/input/event2:      Sleep Button
/dev/input/event3:      Power Button
/dev/input/event4:      AT Translated Set 2 keyboard
/dev/input/event5:      Intel HID events
/dev/input/event6:      PC Speaker
/dev/input/event7:      DLL0704:01 06CB:76AE Mouse
/dev/input/event8:      ELAN Touchscreen
/dev/input/event9:      ELAN Touchscreen UNKNOWN
/dev/input/event10:     DLL0704:01 06CB:76AE Touchpad
/dev/input/event11:     ELAN Touchscreen UNKNOWN
/dev/input/event12:     Dell WMI hotkeys
/dev/input/event13:     Video Bus
/dev/input/event14:     HDA Intel PCH Headphone Mic
/dev/input/event15:     HDA Intel PCH HDMI/DP,pcm=3
/dev/input/event16:     HDA Intel PCH HDMI/DP,pcm=7
/dev/input/event17:     HDA Intel PCH HDMI/DP,pcm=8
/dev/input/event18:     PS/2 Synaptics TouchPad

then after suspend for once, it reports 18 devices instead, the last one "/dev/input/event18" was missing.

But on 6.6.13 or 6.7.0, evemu-describe reports 18 devices just after a fresh reboot, without "/dev/input/event18".
After suspend for once, it would report 17 devices, this time with "/dev/input/event4: AT Translated Set 2 keyboard" missing, and the laptop keyboard stopped working.

Available devices:
/dev/input/event0:      Lid Switch
/dev/input/event1:      Power Button
/dev/input/event2:      Sleep Button
/dev/input/event3:      Power Button
/dev/input/event5:      Intel HID events
/dev/input/event6:      PC Speaker
/dev/input/event7:      ELAN Touchscreen
/dev/input/event8:      ELAN Touchscreen UNKNOWN
/dev/input/event9:      ELAN Touchscreen UNKNOWN
/dev/input/event10:     DLL0704:01 06CB:76AE Mouse
/dev/input/event11:     DLL0704:01 06CB:76AE Touchpad
/dev/input/event12:     Dell WMI hotkeys
/dev/input/event13:     Video Bus
/dev/input/event14:     HDA Intel PCH Headphone Mic
/dev/input/event15:     HDA Intel PCH HDMI/DP,pcm=3
/dev/input/event16:     HDA Intel PCH HDMI/DP,pcm=7
/dev/input/event17:     HDA Intel PCH HDMI/DP,pcm=8

Info of the keyboard (from evemu-describe):

# EVEMU 1.3
# Kernel: 6.6.13-1-lts
# DMI: dmi:bvnDellInc.:bvr1.12.2:bd12/15/2019:br1.12:svnDellInc.:pnXPS139350:pvr:rvnDellInc.:rn09JHRY:rvrA00:cvnDellInc.:ct9:cvr:sku0704:
# Input device name: "AT Translated Set 2 keyboard"
# Input device ID: bus 0x11 vendor 0x01 product 0x01 version 0xabba

I've put dmesg of both good and bad kernels here: https://gist.github.com/rocka/0ed65870e … 96e5a7c4d0

Hello, I was having the same issue with my update to 6.7.0. I have downgraded my kernel to 6.6.10 which works like a charm, To be exact, I did:

cd /var/cache/pacman/pkg
sudo pacman -U file://linux-6.6.10.arch1-1-x86_64.pkg.tar.zst file://linux-headers-6.6.10.arch1-1-x86_64.pkg.tar.zst

Good:

[  121.383254] atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.

Yes it is! I built linux-lts 6.6.13 with that patch reverted, and the keyboard works fine after suspend.
Here's the dmesg: https://gist.github.com/rocka/0ed65870e … tched-good

So I guess it's time to report the issue to kernel bug tracker?

Yup, quite frankly I'm not even sure what might have justified the LTS commit.

I've reported the issue on kernel bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=218424

Re: [SOLVED] Laptop keyboard stopped working after suspend in 6.6.13/6.7.0

Thank you for reporting this and sorry about the trouble.

I have submitted a patch-series fixing this upstream:
https://lore.kernel.org/linux-input/202 … edhat.com/

For now as a workaround I suggest staying with 6.6.12. Hopefully the fixes will get accepted upstream soon and also added to the 6.6.y (and other stable) series.

Thank you for the fix! I will stay with 6.6.12 and mark this thread as solved. Looking forward for it to be merged.

Re: [SOLVED] Laptop keyboard stopped working after suspend in 6.6.13/6.7.0

Just wondering (esp. @hansgoede): Isn't the underlying bug one device vanishing after waking up? And only the patch removing the "dummy" device that took the fall until now?

Thanks for posting this. I had the same issue on a desktop machine, with my keyboard not functioning at all after the update. Downgrading the kernel fixed it.

Re: [SOLVED] Laptop keyboard stopped working after suspend in 6.6.13/6.7.0

This should have been fixed in linux 6.7.5 or linux-lts 6.6.17. Confirmed in linux 6.7.8.arch1-1.
