Can you please provide a bit of extra commentary about the symptoms of
the issue this patch addresses? Like Staale, I'm running a FreeBSD
server which uses mpt for its disk subsystem (SunFire X4100 with 2 x
SATA 2.5" disks in RAID-1) and I've had a series of long running
problems with the performance of the controller. I'm keeping a close eye
on all mpt related commits and hope to find the cause sometime.

Cheers,
Lawrence
