Thanks Harry - that certainly sounds applicable. I'm working on a
system-wide upgrade to 4.9 right now so getting it to work with 4.4 may be
a non-issue. It looks like I should plan on patching 4.9 though!

I'm glad to see that 3ware finally has mention of a new beta driver for
4.8. Maybe they hired a FreeBSD person at last!
