Under 8.2 once MFI sees a timeout it will timeout forever.
I committed major updates to MFI in r247367 & r247369 which deal with
many error condition problems that cause panics. So if your seeing issues
with MFI I'd suggest you upgrade to stable/8.

Subject: Unexpected reboot/crash on 8.2-RELEASE.
I had an unexpected reboot of my Dell R610 today around 2:05-06pm today.
I do not know if it crashed or if it was power cycled.
This machine is running:
FreeBSD gunsight1.neutralgood.org 8.2-RELEASE FreeBSD 8.2-RELEASE #1: Thu Dec 8 21:58:59 UTC 2011
root@:/usr/obj/usr/src/sys/GENERIC amd64
It's a stock 8.2-RELEASE kernel except I had to tweak it near the top of
vfs_mountroot() to delay before attempting to mount the root filesystem.
(Without my tweak it attempts to mount root before the USB drive is finished
getting attached.)
The dmesg shows this at the reboot:
mfi0: 24272 (422106527s/0x0020/info) - Patrol Read complete
mfi0: 24273 (422172000s/0x0020/info) - Patrol Read started
mfi0: 24318 (422192750s/0x0020/info) - Patrol Read complete
mfi0: 24319 (boot + 3s/0x0020/info) - Firmware initialization started (PCI ID
0060/1000/1f0c/1028)
mfi0: 24320 (boot + 3s/0x0020/info) - Firmware version 1.22.12-0952
mfi0: 24321 (boot + 3s/0x0020/info) - Firmware initialization started (PCI ID
0060/1000/1f0c/1028)
mfi0: 24322 (boot + 3s/0x0020/info) - Firmware version 1.22.12-0952
Does this mean the machine did not lose power? I ask because my datacenter
had some sort of power incident and I'm not sure if the server lost power
or not. But if the kernel message buffer from before the incident is still
present then the machine never lost power, correct? The datacenter's power
incident I'm told happened somewhere around the time of the reboot so I
have to ask.
It looks like I didn't have dumps enabled. That's ... not helpful.
The machine has been stable for:
2:05PM up 472 days, 21 mins, 7 users, load averages: 0.01, 0.02, 0.00
http://www.neutralgood.org/~kpn/dmesg.boot
Here's various stats I usually keep displayed. This is the last from
before the reboot:
http://www.neutralgood.org/~kpn/status.txt
I've got all the power savings features turned off in the BIOS and, like
I said, the machine has been stable for all this time. However, one thing
to note from a couple of days ago:
