I archived my config and git hash.
I can't easily post an Oops: under X it doesn't even appear -
machine freezes immediately, and under non-KMS console it is
possible to get one, but difficult to screen-shot (using bare
metal, not VM). Also the Oops was seemingly unrelated.
And if you run "dosemu -s" under non-KMS console, you'll also
reproduce this one:
