giving up on X buffers

Hi,

I have a machine that (for the most part) sits idle. 
It's running -current right now (info at the bottom)
and every time I reboot, I get the message "giving up
on x buffers" and when it boots, it tells me the (on
all mounts) "not properly dismounted".  I have an
extra HD laying around that I've been meaning to throw
in there and see if it's a HD problem, but I wanted to
know if there is any way to debug this?  I have
another computer running the same current (I cvsup
them both at the same time so they are identical as
far as source goes, for testing) and it reboots fine.
