That workaround seems to work for me. Over an hour of uptime without any
screen freezes.

(I first tried fiddling with /sys/module/i915/parameters/enable_psr at
runtime, but that apparently has no effect. Should that file be read-only?)

Feel free to ask me to test a fix (or a revert) once you've figured out what
to do about this.
