Looks like we're on different hardware. Mine is SAS and yours is SCSI

mpt0: <LSILogic SAS/SATA Adapter> port 0xec00-0xecff mem 0xdffec000-0xdffeffff,0xdfff0000-0xdfffffff irq 16 at device 0.0 on pci2
mpt0: [ITHREAD]
mpt0: MPI Version=

da0 at mpt0 bus 0 target 8 lun 0
da0: <LSILOGIC Logical Volume 3000> Fixed Direct Access SCSI-2 device
da0: 300.000MB/s transfers
da0: Command Queueing Enabled
da0: 476837MB (976562176 512 byte sectors: 255H 63S/T 60788C)

I have however noticed that the events only occur at specific times. So far I have noticed them only at boot time just after dmesg identifies the adapter and also whenever I try to install/upgrade a port.

It doesn't matter what port it is but here is an example (seen as I'm having trouble with the mysql port not compiling but that's for a different thread)

# make
===>  Extracting for mysql-client-5.0.75
=> MD5 Checksum OK for mysql-5.0.75.tar.gz.
=> SHA256 Checksum OK for mysql-5.0.75.tar.gz.
#######Long pause here of >30 seconds with the mpt0 errors being logged
===>  Patching for mysql-client-5.0.75
