Suspend entry fails on Ryzen 5900HX

Brief summary of the problem:

The problem arises 100% of the time when I try to suspend using s2ram: the screen blanks for a few seconds and then wakes up with a message s2ram_do: Connection timed out. Kernel logs show this block of errors, and only these:

[  405.490464] amd_pmc AMDI0005:00: failed to talk to SMU
[  405.490479] amd_pmc AMDI0005:00: failed to adjust keyboard wakeup: -110
[  405.490481] amd_pmc AMDI0005:00: PM: dpm_run_callback(): acpi_subsys_suspend+0x0/0x70 returns -110
[  405.490488] amd_pmc AMDI0005:00: PM: failed to suspend: error -110

This resembles a number of other issues previously reported to have been fixed in linux-5.x kernels, but is apparently different.

How to reproduce the issue:

Either with AC or battery:
