Thinkpad 40AJ docking station issues

Hi,

I have two issues with the Thinkpad 40AJ docking station that results in connected displays receiving "no signal" and the docking station not working after unplugging and replugging it.

amdgpu dmesg errors that result when attempting to connect a display:

Re: Thinkpad 40AJ docking station issues

Can you also reproduce these failures with the regular "linux" package?

Re: Thinkpad 40AJ docking station issues

Yes, using the linux and even linux-lts kernel I've seen some online reccomend results in the same error.

Re: Thinkpad 40AJ docking station issues

Could you see if the issue is also present on the already released (but not yet packaged) 6.13 kernel? AMD graphics stuff is under heavy development, so it might already be fixed in a newer version

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

Re: Thinkpad 40AJ docking station issues

Sadly, the issues still persist even with using the mainline kernel.

Re: Thinkpad 40AJ docking station issues

Does it work with the linux-lts kernel?

No. Still doesn't work.
