@Koba, Thanks for your help. I have tried the kernel from #55. sudo cat /sys/bus/pci/devices/0000\:58\:00.0/d3cold_allowed showed "0". The suspend & resume did end up in a freeze. I have attached dmesg (journalctl -k -b -1 on next boot). Just as a note I saw the power consumption during suspend was around 1.0W compared to 0.5W using the 5.10-oem-1025 and "echo 0 | sudo tee...." from #51. This was using an external AC power meter - so it includes the power loss in the AC adapter.

The measurement is 5-10 min after boot/resume - looking at "top" to see system was idle. This is consistent - I have tried more that 10 times. BIOS is updated to latest version. I have checked power consumption with external meter - and confirmed that it is higher. I have attached output of: sudo powertop -t 60 -r --html=before.html (and after) I have noticed that Package C-state 6 is reached before suspend but not after. I expect that idle power consumption after suspend should be the same as before.
