Kernel Panic __mp_lock_held in kern_lock.c when using vmt0

[s.small]

Hi all,

We have a problem with some machines running on ESX, apparently mostly  if a
SAN is used. The appliances crash with a kernel panic (see attached
screenshots) after a few hours or days.
The machines run stable if vmt is disabled in the kernel.

The architecture is i386, and usually we can see messages like

Aug 29 11:56:58 UI-SRV-MCR-01 /bsd: vmt0: failed to send reset reply
Aug 29 11:56:58 UI-SRV-MCR-01 /bsd: vmt0: resetting rpc

in dmesg.

ESX Version are from 5.0 to 5.5 and with different machine type settings.

Cheers
Steven
