Hi All,
The lastest Git kernel doesn't boot anymore after the latest DRM
updates (drm-next-2024-09-19). [1]
I tested it with an AMD Radeon HD 6970 (Cayman XT) and with an AMD
Radeon HD 5870 (Cypress XT).
I reverted the DRM updates and after that the kernel boots without
any problems.
Please note: Due to a lack of time, I can't do a bisect.
Please check the latest DRM updates.
Thanks,
Christian

I replaced the new Radeon DRM driver from the Git kernel with the
Radeon DRM driver from the kernel 6.11. (cp -R
linux-6.11/drivers/gpu/drm/radeon a/drivers/gpu/drm/)
It compiles without any problems but unfortunately the kernel doesn't
boot either.
Have you tested the new Radeon DRM driver with AMD Radeon graphics cards?
Maybe this is the issue (included in the latest DRM updates -
drm-next-2024-09-19):
