All the 6.1 kernels have the same behavior.

It's alright. The 5.10 works. Hopefully when 6.1 gets upgraded they will have one without PREEMPT_DYNAMIC to try.

I will mark this solved.

Strangely enough, the 6.1.0-11-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-4 (2023-08-08) x86_64 GNU/Linux is the up-to-date default kernel.

@Jorge: you might try one of the earlier 6.1 kernels.

I suspect the PREEMPT_DYNAMIC kernel. I have one system I use to run CUDA (on a Nvidia card) where I have to boot it with the default kernel, not the preempt one, to get CUDA to work.

If you have an option to boot the 6.1 default kernel could you try it to see if that's the problem?

I rebooted with the 5.10 kernel, it works:

uname

Linux Oya 5.10.0-23-amd64 #1 SMP Debian 5.10.179-3 (2023-07-27) x86_64 GNU/Linux

With the default 6.1 kernel it does not:
uname

Linux Oya 6.1.0-11-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-4 (2023-08-08) x86_64 GNU/Linux

so something broke, for this particular machine, in 6.1

I tried downgrading the firmware to the version that is on Chimaera (20210315-3), rebooted. No change.

Thanks. I tried it, apt-get returns

firmware-amd-graphics is already the newest version (20230210-5).

Maybe just the package firmware-amd-graphics is missing. The mean thing is that since Bookworm the non free firmware has moved to a new sub-repo non-free-firmware. Daedalus had to follow Debian.

https://wiki.debian.org/Firmware

You need to add this to your sources.list. Give it a try.

I upgraded 1 machine to Daedalus with no problems.

On the second machine I have very low screen resolution.

Xrandr:

I have tried reinstalling the radeon drivers. I have set GRUB_GFXMODE to 1920x1080. I have searched online but have not found a solution.

Using a Gentoo rescue disk the resolution is correct. It was correct under Chimaera.

Any help appreciated.
