"Kernel regressions" was a little bit too generalizing in this meme. Technically drivers that became part of the kernel can also regress, as recently seen by users of Corsair Void wireless headsets (an unpatched 6.13 kernel is panicing once the headset adapter is plugged in).
Broken driver. It now seemingly attempts to read the current battery status, and while doing so literally locks up (not sure what "locking" means in context of a Kernel, but it's somehow involved).
Interesting! Do you have checked the kernel log (there should be a backup from last session somehow iirc) , and do you know the name of the kernel module as well as your kernel version?
I want to check that code out if I see where it fails exactly
Or have you documented that issue already somewhere?
Linus likes to break driver interfaces every other Tuesday though. Meaning you can get stuck on an old kernel version, depending on your hardware. This happens pretty regularly for ARM based boards for example.
