Kernel panic with with 6.10.0-3 on Lenovo thinkbook-13x-gen4 (Intel Core Ultra 9)

Support Kernel
1

Everything was working fine until the 6.10rc versions, but ever since the update to 6.10.0-3 kernel panics happen randomly roughly twice a day (blinking caps lock, everything frozen). journalctl does not seem to report anything. If this is known and has been fixed already I’m happy to wait for the next kernel update. If not, how can I debug it and report it? New Manjaro user here.

Note that switching to a lower kernel is not an option: I am on a Lenovo thinkbook-13x-gen4 (Intel Core Ultra 9) which is too new: 6.10 still does not fully support it and lots of things do not work on 6.9.

No guarantees - in my opinion - worth a try

Switch to unstable

sudo pacman-mirrors -aS unstable
sudo pacman -Syu

Thanks @linux-aarhus. Unfortunately it keeps occurring even with the newer kernels (even on pure arch and with the Linux mainline kernel it seems), see here for a discussion:

https://github.com/craigcabrey/thinkbook-13x-gen4-enablement/issues/8

It seems like in Fedora it is working fine so the Fedora developers have likely found the solution. The answer thus probably lies somewhere in the Fedora 6.10 kernel patch:

https://src.fedoraproject.org/rpms/kernel/blob/f40/f/patch-6.10-redhat.patch

However, I am no kernel developer. Is there a way to report this as a bug for someone from the Manjaro team to look into? I’d be happy to provide debug info from my laptop to help nail this down.

Then it will - possibly - be posted as patch to upstream kernel.

Neither am I and the kernel code is a mystery and completely beyond my paygrade :slight_smile: I envy those capable of understanding the code.
