Black screen when booting into 6.11 kernel

HI,

some time ago I updated kernel package to 6.11, unfortunately I couldn't boot after that. There was a black screen just before prompt for disk decryption.
I tried live arch iso with kernel 6.11.5, and booting it resulted also in black screen, then I tried iso with 6.10.10 and this worked.
I installed and been using linux-lts, but this problem still happens on 6.12.1.
I want to do some more investigation, but journalctl and dmesg is of course empty until I boot into working kernel. What can I try now?

My hardware:
ryzen 3 1200
radeon hd7750

Thanks for replies.

You can inspect the journals of previous boots with journalctl's -b option. Also is the issue also present on the latest release candidate?

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.13rc2-1-x86_64.pkg.tar.zst

Re: Black screen when booting into 6.11 kernel

I checked

journalctl --since today | grep "Linux version"

it returned only logs from linux-lts.

Kernel you provided boots fine. Do you know what was the fix? I hoped I could do some coding this time

Thanks for help.

No I don't know what the exact fix for your issue is, but the Graphics stack is usually under heavy development, hence why I thought testing the release candidate might be worth it.

If you want you can "reverse bisect" to find the commit that fixes the issue:

git bisect start --term-new=fixed --term-old=unfixed
git bisect fixed <version>
git bisect unfixed <version>

https://stackoverflow.com/questions/154 … ood-commit

Then afterwards you could propose this patch to be included in the stable tree if it is easily backportable.

Re: Black screen when booting into 6.11 kernel

By now we have a stable kernel from the 6.13.y series (just install the 'linux' package), so if it's the same issue it should be fixed by just getting the latest version of that package
