Re: Regression report on laptop suspend

Hi, this is your Linux kernel regression tracker speaking.

TWIMC: Christian afaics is plagued by an older issue wrt suspend: "
Touchpad is not working anymore after suspend to RAM since kernel 5.14 -
AMD Ryzen 5 4600H". For details see:
https://bugzilla.kernel.org/show_bug.cgi?id=214667
https://lore.kernel.org/regressions/12b9a10a-626b-cafd-05d6-cf0a116aa39b@leemhuis.info/

I wonder if that might interfere somehow and if there is a easy way to
rule that out (I wonder if unloading the hid modules involved is a good
idea or stupid advice -- I fear it's the latter).

Ciao, Thorsten

P.S.: As a Linux kernel regression tracker I'm getting a lot of reports
on my table. I can only look briefly into most of them. Unfortunately
therefore I sometimes will get things wrong or miss something important.
I hope that's not the case here; if you think it is, don't hesitate to
tell me about it in a public reply, that's in everyone's interest.

BTW, I have no personal interest in this issue, which is tracked using
regzbot, my Linux kernel regression tracking bot
(https://linux-regtracking.leemhuis.info/regzbot/). I'm only posting
this mail to get things rolling again and hence don't need to be CC on
all further activities wrt to this regression.
