To reproduce the issue, I created a Ubuntu 20.04 VM on Azure (the kernel version was "5.4.0-1022-azure #22-Ubuntu"), and I ran "echo disk > /sys/power/state" in the VM and then checked the Azure serial console of the VM and found the warning in commen #8 and suspending couldn't finish normally (it looks the VM got a fatal page fault error later). I suppose the issue can also repro on a local Hyper-V host.
