<pre>Just had a hard lockup on my haswell (Macbook Air 2013).
Probably really hard to reproduce, but I thought I would report it anyway.
Attached is the dmesg, it spans across 24 hours, including around 23 hours of
suspend, you can see a lot backtraces before the suspend and so much after the
wakeup that it's probably what triggered the lockup.
It looks like pretty much all write to registers trigger a backtrace.
I thought it would be interesting for the record, even if nobody can reproduce.
