I looked at recent changes in drivers/input/keyboards/atkbd.c and suspected https://github.com/torvalds/linux/commit/9d17ad2369dcc9beda0785cf5960222dbdd6c9df for a bit, but disabling it does not help, and it does not seem to be in 5.4.150. (In reply to hkBst from comment #0) > In gentoo-sources-5.4.15 I meant 5.4.150... I looked briefly at drivers/acpi/acpica/psparse.c and its recent changes, but I could not find anything relevant... I tried 5.4.11, but no change from 5.4.9. These are old kernels. Can you try 5.15.0 and see if it's been fixed? Do you have a dmesg from the working kernel and nonworking to compare? (In reply to hkBst from comment #4) > I tried 5.4.11, but no change from 5.4.9. Sorry, I seem to have a knack for butchering these version numbers. I meant 5.14.11 and 5.14.9 here. So latest available when I reported earlier. Anyway, I'll report back on 5.15.0 soon.

dmesg of kernel 5.15.0 (non-working brightness keys)
Booted kernel 5.15.0, but brightness keys are not working.
Created attachment 749502 [details]
dmesg of kernel 4.19.214 (working brightness keys)
Booted kernel 4.19.214, the latest version with working brightness keys.
Can you do a git bisect between a the last working kernel and the first non-working kernel Today, I upgraded to 5.15.118-gentoo and brightness keys are still not working. I gave bisecting the kernel a try, but the built kernels just seem to hang instead of booting. I followed these steps from the wiki: # git clone --shallow-exclude v4.19 --branch v5.15.118 git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git linux-stable # rm linux && ln -s linux-stable linux # cd linux # git checkout v5.15.118 # cp ../gentoo-config ./.config # make olddefconfig # make -j4 && make install # grub-mkconfig -o /boot/grub/grub.cfg and reboot choose new kernel from grub menu hangs at printed message from grub about loading kernel Some help would be appreciated...

Follow these directions http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/ Sorry if I was unclear. I think I have understood the mechanics of bisecting, but the vanilla kernels that I've built from the same config as I am using for gentoo-sources do not seem to want to boot. The only difference would seem to be the gentoo-patches. Is there anything from gentoo-patches that would explain that? Is this about brightness or booting? It is about booting. |
