In rc4, the number of warnings has dropped dramatically.
No more errors "kasan slab-out-of-bounds" and no "DMA-API device
driver failed to check map error".
But still not fixed "sleeping function called from invalid context at
include/linux/sched/mm.h:196" and "BUG: key ffff88810b0d9148 has not
been registered!"
Second issue Navi specific because it started to happen in 5.10 kernel
after replacing Radeon VII to 6900XT.

Issue with the switching off monitor still happens too, but messages
in logs become more detailed:

I hope "[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to process the
buffer list -4!" gives an idea of what happened.
