Cannot shutdown, fsc on every bootup

[Rob Henry]

I was unable to search this bug list. Internal Server Error
I have recently upgraded from 6.x of PCBSD to 8.1 which is FreeBSD 8.1
I have many performance and stability problems now. The first I want
to address is a hang during shutdown that causes a file system check
every time I start up.

Hardware is supermicro mother board circa 2002 with dual xeon
RocketRaid 182x raid controller
ati radion 8xxx video

It appears to sync the disks, the last message is waiting for 'htp_wt'
to stop... done

then nothing...

Any advise?
