Hi,
another release cycle, and another regression.
After another kernel update in Fedora Rawhide GPU not
entering in graphic mode on my laptop ASUS ROG Strix G15 Advantage
Edition G513QY-HQ007.
And in kernel log appears this bug trace:

drm/amdgpu: bypass RAS error reset in some conditions
PMFW is responsible for RAS error reset in some conditions, driver can
skip the operation.
v2: add check for ras->in_recovery, it's set earlier than
amdgpu_in_reset.
v3: fix error in gpu reset check.
