Not sure the events are related, but it does appear that you have the mpt
driver's debugging enabled. Have you been booting with -v, or have the
mpt_debug kernel environment variable set in loader.conf, or setting
something in sysctl.conf?

The lights-on thing would seem to be some sort of bus freeze, like a BDR
from a device.  Since you're using a disk enclosure, is it reporting any
problems accessing any of its disks?  perhaps there's a bad cable or
device going down in the enclosure?

I have an x335 here, which is the ATA version of the x345, yet the MPT is
still on the board. I plugged it into a couple of disks for testing and it
worked, except if I enabled the Integrated Mirroring (IM) which requires
OS support.
