I've done the full-upgrade and disabled the non-Ubuntu extensions and then re-triggered the crash with `echo mem > /sys/power/state`. This now causes a hard hang of the whole system - its no longer accessible over the network when it tries to wake up. There is no new log in /var/crash and the last thing in kern.log is it going to sleep. This doesn't seem promising.
The kernel is a custom-built 5.9.0 built from Linus' repository - I'm not expecting a lot of support with that.
