Comment(by dsd):

 The attached testchrome.py program seems to keep the 3D engine busy and
 can also reproduce the crash - the first time we've seen it outside of

 Test procedure (on unmodified 12.1.0 build 18):
  1. systemctl stop prefdm.service
  2. (on VT) xinit /path/to/testchrome.py
  3. (on serial console) while sleep 1; do rtcwake -m mem -s 7; done

 It will crash in less than an hour, during system resume or very soon
 after. (and like runin, if you run the modified gfx driver with debug
 messages, it'll crash much quicker)
