FreeBSD nasbox.tpaktop.com 9.0-RC3 FreeBSD 9.0-RC3 #0: Sun Dec  4 08:56:36 UTC 2011     root at farrell.c se.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64
>Description:
On barebone must be installed ESXi hypervisor 5.0. Over ESXi I'm trying to install or even use already installed VM with FreeBSD 9.0 RC3 (8.2 has the same symptoms). The main condition is - using physical controller LSI 1086 as passthroug device, configured at ESXi thru VT-d technology and it has to be added to FreeBSD virtual machine as PCI device.

As only booting procedure reaches mpt driver loading I've got these errors:

And after 300 seconds booting looks to be freezed finally.
>How-To-Repeat:
Try to boot FreeBSD over ESXi with passtrough LSI controller device which is calls mpt driver.
