Subject:   FreeBSD on VMware ESXi with PCI Pass Through enabled

Just curious if anyone has any good recommendations of settings for 
running FreeBSD under VMware ESXi 5.1 with PCI(e) pass through enabled.  
I have been doing some initial testing with a new motherboard processor 
and RAM.  That I am hoping to be able to run 3 Servers on.

The intended virtual machines for the setup.
1.) A FreeBSD system to run Bacula, which will require PCI pass through 
for an eSATA drive dock so backups volumes can be Rotated.
2.) A FreeBSD system to host my web/email server, no pass through 
required.
3.) A FreeNAS box host SMB shares and iSCSI, will use a PCI pass 
through to allow direct access to 4 Hard drives, attached to a separate 
SATA controller.

Current Hardware Information:
eSATA Controller for backups:  Koutech IO-PESA111 PCI Express SATA II 
(3.0Gb/s) - uses Silicon Image 3132 Chipset
System Board:  ASUS F2A85-M PRO FM2 AMD A85X (Hudson D4)
CPU:  AMD A10-5800K Trinity 3.8GHz (4.2GHz Turbo) Socket FM2 100W 
Quad-Core Desktop APU (CPU + GPU)
RAM:  CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 
(PC3 12800)

I still need to add an additional controller SATA controller for the 
FreeNAS VM, but so far testing with a new machine built for the Bacula 
install has only been consistently able to trigger a complete core dump 
and crash of the ESXi host machine, sometimes at boot of the VM with PCI 
pass through, sometimes not until a load has been applied to the 
external hard drive on the Pass through SATA controller.

I have tried the following things to fix this that I have come across 
while searching for help.

Added the following to /boot/loader.conf:
   hw.pci.enable_msi=0
   hw.pci.enable_msix=0

Added the following to the Vmware Virtual Machine Configuration:
   pciPassthru0.msiEnabled = "FALSE"
