Dear Ubuntu maintainers, I think I found a regression in linux 5.15.0-105.
In the past few days, my keyboard stopped working after waking up from suspend (sleep), so I couldn't unlock my laptop. Various workarounds found on the internet helped, but I wanted to investigate if it was a gdm issue, grub, or a hardware failure. I managed to narrow it down to the kernel, which is why I'm filing this bug report.
AFAICT the only keys that work are the keyboard lights and the brightness knobs (in the Fn functions). I can confirm that 5.15.0-105 has the issue, and I can consistently reproduce it with the following steps:
1. boot fresh with 5.15.0-105
2. login to my account
3. choose suspend from the power menu
4. wake up
Following the same steps above with the last kernel available does not cause the issue (package version 5.15.0-101.111). I'll keep using that one for the time being.
