Heya everyone.
I have a Talos II with an AMD Radeon PRO WX 9100 (Vega 10 XT, connected to a monitor via DP to HDMI). I've tried several distros on it, but currently it has Debian Bookworm installed (I know Debian best but I would happily switch to another distro if needed).
Everything is fine if I build and use the 5.5 kernel from Raptor's git site - I'm typing this on Firefox LTS in Cinnamon/Xorg. I've set the boot console to be VGA in Petitboot and added console=tty0 to the grub command line. Otherwise there's nothing different or special about this setup.
If I try any other kernel, with 4k or 64k pages and any combinations of kernel boot arguments, the screen drops out some time after the kexek message from Petitboot. I can ssh in, and see that the amdgpu module is loaded, but if I try to start Xorg it complains about no matching screens (or devices, if I remove the xorg conf snippet that specifies amdgpu as the default - 5.5 doesn't need this, though).
I'm happy to use 5.5 for now but at some point I'll need to upgrade to a newer kernel.
Can anyone recommend another known-good combination of kernel and configuration for Vega 10?
Thank you.
- Rhea.
