BUG spinlock lockup, rtc related, 3.0-rc7+
From: Ben Greear
Date: Wed Jul 13 2011 - 13:29:21 EST
This is on the same nfs testing machine I've been posting about. This
has some additional nfs patches included, running tests to mount, do io, unmount
over and over again. Seems that the NFS bugs might be finally fixed, but
system is still un-stable in general when under load.
This info was printed after several other warnings that I previously posted
to lkml.
This one appears to lock up the machine pretty badly though...can't ssh into
it anymore, and similar messages keep spewing every few minutes.
I *think* the BUG at the end of this email is the important part, but
maybe it's just a symptom of something else...
lockdep has already been disabled due to the issues it finds in
scheduling (already being discussed on LKML in a different thread).
