I've tried to again reproduce this problem on my box by downgrading to
libdrm 2.4.18 (and a few other hacks). But that bug simply refuses to show
up again, here. Can you and Bruno please gather a few backtraces (as many
as you have lying around in your logs) and upload them to this bug?

Perhaps I can see a pattern and get a clue what's going on - at least that
way I've managed to fix the other problem with the stuck chipset flush.
