Problems with Tuxedo Pulse 15 Gen1 waking from suspend

Hey y’all!

Since upgrading from 22.05 to 23.11 (I know, quite a jump!), my Tux Pulse 15 Gen1 outright fails to wake from suspend. Or rather, what is happening is that the screen and keyboard both come up and then I get the capslock key blinking furiously forcing me to do a hard reboot. Anyone perhaps has/had this problem? I seem to be able to correlate it with kernel upgrade (5 → 6) - it didn’t happen on 22.05 with kernel 5.*, but that’s it. journalctl is pretty silent on any indications of what the issue might actually be:
