There's newer vendor driver and firmware.

http://www.3ware.com/support/download.asp

1.  Driver

Select 9550SX series (not 9000 series) and download 9.3.0 version for 
FreeBSD.  It contains newer driver source and binary, which seems to 
work pretty well with 9000 series controllers as well.

2.  Firmware

Select 9000 series and download 9.2.1.1 version, which also seems to 
improve stability.

This driver is directly supported by 3ware.
