14.0 RELEASE drm kmod amdgpu kernel panics

hello world :-)

i have upgraded to 14.0 RELEASE p6 and after recent pkg update i notice
random drm kmod amdgpu (515 on rx570) hangs several minutes after i run
desktop environment making workstation useless.

nothing like this happened before on 13 and probably right after upgrade to
14.

this may be correlated with running firefox. until i run firefox all seems
to work fine.

did anyone observe such problems recently?
