I get the exact same problem.  SuperMicro PIIIDME (uses Intel 840
chipset), Adaptec 29160 (64-bit), with a Seagate Cheetah 36G U160 10K
RPM drive on the LVD segment.  On the SE segment is a Plextor PX-40TS
and a Yamaha CDRW (I forget the exact model number.)  

Kernel is 2.2.15 patched up to 5.1.29.  

When this happens, all reading and writing to the disk are effectively
stopped.  From what I can tell there's _some_ I/O going, but it's such a
tiny stream that you're more likely to hang the kernel or some integral
process with paging issues than you are to to be able to shut down
before this happens.  I usually end up just hitting the reset switch.  

If there's anything else I can report to help dianose this, I'm more
than willing.
