Well *that* is rather interesting. We have considered dropping Alpha support because we couldn't find somebody with that hardware any more.
The patch you mentioned has the following bug fix associated with it: commit e0658f970a7f3d85431c6803b7d5169444fb11b0 Author: Christian König <christian.koenig@amd.com> Date: Tue Jan 5 18:55:47 2021 +0100 drm/radeon: stop re-init the TTM page pool Drivers are not supposed to init the page pool directly any more. Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> Link: https://patchwork.freedesktop.org/patch/412153/Please make sure that you got this, but when 5.11.11 doesn't work either I would expect that.
Do you have a full dmesg of the system? Thanks, Christian.

Problem is, I don't have a 64-bit system with enough disk space to do the kernel builds with a cross-compiler, and local (native) builds on the PWS are taking 36+ hours each these days. Unless I get *really* lucky with the bisects, the task will take a couple of weeks.Confirmed that v5.11.0 hard locks up on presenting the X-Desktop login screen whereas v5.10.0 is fine.
