12v 4.6 Mesa 20.3.4 12direct render Yes Describe the issue
On boot, amdgpu crashes before Plymouth/Gnome can load, and hangs the system until I perform a hard reset. Frequency seems related to kernel versions - 5.10.10 generally does not crash, 5.10.11 crashes every time, and 5.10.12 crashes about 50% of the time. Occasionally, the system will get far enough that Fedora's built-in error reporting catches it - this is the automated report filed from my system: https://bugzilla.redhat.com/show_bug.cgi?id=1924384
I am running an unmodified kernel, and I have not moved away from the default Mesa included with Fedora. I typically run with amdgpu.ppfeaturemask=0xffffffff enabled, but this crash appears with similar frequency if I remove that kernel option.
Regression
This issue first appeared when Fedora offered kernel 5.10.11 as an update. This update coincided with Mesa 20.3.4 being offered as an update (1 Feb 2021). Before this update, I did not experience this problem.
