I've been seeing strange lockups since 3.7.4. Not so easily reproducible
most of the time. Previous lockups looked to be rcu/rtnl based, but the one
below has a bunch of i2c stuff in it.
Patches applied are a few wifi patches from upstream and one hack to make
ath9k able to over-ride the eeprom regdomain.
I *think* the decodes are proper, I had to switch back to this patch
set and re-compile....

I saw another lockup, in a similar spot (but no i2c stuff this time).
I had also recompiled so that it would not panic on lockup, and by the
time I noticed the problem, it seems the lockup resolved itself and
the system was stable.
So, maybe a false positive on the lockup detector, or maybe
it really was locked for a while but then recovered...
Thanks,
Ben
