Same bug, not fixed yet. I'll see if I can get it fixed on monday, I've
seen it here a few times as well. Seems not to be easily reproducable
and no real pattern to when it does. In the mean time, you can replace
the BUG_ON() with a

if (cfqq->allocated[crq->is_write] == 0) {
WARN_ON(1);
cfqq->allocated[crq->is_write] = 1;
}

and the system should work fine.
