Summary of log: tests were performed on 22 January.

The boot was at 20:36.  Maybe those 10 minutes came from NTP or
something.  Next boot:

Anyway, the page table seems to get corrupted when X starts.

Could you send a log from booting and starting X with drm.debug=6 on
the kernel command line?

Thanks,
Jonathan
