Public bug reported:
When I resume from suspend, my system initially appears to be frozen.
The screen is black and/or the input devices are not working.
After several minutes, I can switch to a console (and then to the
desktop) but the system is under full load, to the point that even
trivial commands will take up to three minutes to execute.
The only way out of this situation is to do a reboot.
I see that dmesg is showing an NVME related stack trace and then the
repeating message "timeout, completion polled".
I ran into the same issue a few months ago when I started using my
current motherboard (ASUS Prime x470-PRO). It got solved by flashing my
BIOS to the latest version. ASUS have not put out any newer since then
so I guess this will require a kernel fix.
