ZFS panic on import under VMware

[Michael Dexter]

Hello all,

I have encountered a FreeNAS under VMware system that gives "ONLINE" 
status for a pool with 'zfs import' but panics when a -f import is done 
under FreeNAS 8.3 x64, FreeBSD 10 and Solaris 11 live DVD. The host 
filesystem passes all checks.

The panic reports:

Stopped at traverse_prefetch_metadata+0x44: movq 0x50(%rax),%rcx

I have posted screen shots of the import, panic and backtrace output:

Any suggestions?

Thanks,

Michael
