9f BSOD/Crash

Here's the minidump.  For a long time the culprit was sbp2port.sys - I never solved that one either.  Now it seems to be disk.sys.  Can't find enough information.  I get a BSOD at lease once a day.  I'm using Vista Ultimate.  Thank you.


Use !analyze -v to get detailed debugging information.
