Bug Description

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.

UPDATE: this would appear to be happening only when I run my CPU in powersave mode (reduced speed and 4-6 vCPUs disabled).

I am including the output of the dmesg command as ran immediately after resume from suspend - it shows the stack trace I am referring to in my bug report.
