Yeah, our ServeRAID driver lacks recent important updates from FreeBSD-CURRENT
including newly supported controllers and a few bug fixes. The update
in FreeBSD-CURRENT also involves converting some of mutex operations into
sema_* and bio*, but I haven't managed to rewrite it using our native
thread APIs. Anyway, I can post a minimal patch(that is, not including my
experimental code to convert the mutexes and the semaphoe stuffs) to support
newer controllers if you like to try it.
