Here is the beginning of my tests so far from an xterm:

During my tests mentioned here, the freeze on wakeup/resume has not been triggered. (However, the freeze still happened several hours earlier when gdm3 was showing its login screen, then automatically went to sleep, and then I tried to wake it up by hitting some key.)
What next? Reboot with some nondefault kernel parameters, or hunt down “xHC error in resume”, or do anything else?
