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. http://www.freebsd.org/cgi/query-pr.cgi?pr=105134
