Bug#987388: Crash of amdgpu on Debian 11 Bullseye
Package: xserver-xorg-video-amdgpu
Version: 19.1.0-2
Severity: critical
Hi.
Today I reinstalled a machine on Debian 11 Bullseye from testing (it was on Debian 10 Buster) and I had a crash of the AMD R9 380.
I could no longer change tty and Xorg was frozen, I could only move the mouse, the keyboard shortcut to reboot the kernel was not working.
After manual shutdown (electrical) I found undred lines of this in syslog:

(here I was typing on the emergency kernel reboot shortcut on keyboard)
I don't know what could be the reason for this.
But the problem has never occurred on Debian 10 Buster.
Thanks.
Max.
