Hi, i have noch kernel 5.4 rc6 installed and the problem didnt change.
I have written AMD_DEBUG=nodma and NOT AMD_DEBUG="nodma" in /etc/environment.

Now i have added the amdgpu.gpu_recovery=1 attribute in grub.

So now there is a long output from dmesg while nothing done then clicking
"login" in bugzilla with firefox.

see attachment dmesg_with_gpu_recovery enabled....

I hope this helps a bit...
