Yeah, if anyone can somewhat reliably reproduce this (you need to
disable rc6 on ilk to not hit another issue which seems much easier to
hit) and bisect it, this would be _very_ much appreciated - we've
pretty much tested all possible "disable stuff" and "revert random
patch" we could thing of, and we can't reproduce these hangs no matter
how hard we bang our heads against this. Atm we're trying to come up
with ways to dump more debug information, but with no clue whatsoever
what's going on that's slow-going.
