I'm afraid to report that I experienced a hang on boot today, using the drm-tip kernel ("5.7.0-994.202005192206"). This time the hang occurred before the LUKS password prompt to unlock the root filesystem. There was a message printed to the screen, which I will attach shortly.
I was able to reboot with SysRq SUSB sequence and the laptop booted fine next time.
