Synopsis: 'panic: lockmgr: thread ... not exclusive lock owner' on SMP Alpha EV6 machine

State-Changed-From-To: open->closed
State-Changed-By: jhb
State-Changed-When: Wed Nov 3 13:30:11 UTC 2010
State-Changed-Why: 
Other platforms have not reported problems with this, so I do not think
this is MI.  This could possibly have been due to insufficiently strong
memory clobbers in atomic operations (if so, that might also have explained
instability with PREEMPTION enabled).  However, since Alpha development has
stopped, this will not be fixed.
