Subject: [BUG] general protection fault, probably for non-canonical address
 0xfe5d6f0af7831e5e: 0000 [#1] SMP NOPTI (5.7RC4 GIT 79dede78c057)

Hi folks.
I didn’t do anything unusual, I just restarted the computer after the
update, launched all the applications that I usually launch and went
to drink tea.
When I returned, I found that the monitor was on (it should have
turned off since I had set the energy-saving mode for 5 minutes in DE)
I tried to move the mouse, after that I realized that the computer was
completely frozen. Even Alt+PrnScr+B did not helped reboot computer.
I decided to fill the bug report here since this is a really serious problem.

I think this issue related to amdgpu driver.
Can anyone look into it?

Thanks.
