Have you dealt with the 'could sleep' stuff with witness turned on? These
are *guaranteed* panics if the system is low on memory at that given
instant. (Witness doesn't cause the problems, it reports fundamental
problems that are already there. The system will panic regardless of
whether witness is there or not.)
I suggest you turn WITNESS on, and stress the system. If you get *new*
'could sleep' stuff or other lock order problems, then there are still
significant regressions to be fixed. The last thing we need during the
'please stabilize 5.0' drive is newly added problems. If other folks are
seeing new ones, please report them here (not to me, I already get too much
email :-]).
Cheers,
-Peter
