New submission from G.Isenmann <gisenmann at web.de>:
Hi!
Since the upgrade to 2.11.0.749 (was 2.10.1) I get regular panics
during make buildworld on this virtual system running on vmware.
It is always this MPT_LOCK_ASSERT in sys/dev/disk/mpt/mpt_cam.c:1242.
Get this between a few minutes and over half an hour after starting
make buildworld. Maybe the probability for the panic depends somewhat
on the activity on the other vmware guests.
