Unexpected reboot/crash on 8.2-RELEASE.

Sun May 19 10:52:04 UTC 2013

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.
