with 2.3.99 I got spinlocks and exeptions... everytime I was using IRQs
massively (heavy networking as transfer 100MB, or moving 100MB of files
from one HD to another) the system froze... When I have put the DAT even
worst. DAT problem was hw problem and not software. Now compaq gives an
extra SCSI controller if you buy a DAT for ES40... But if you install
another SCSI controller, you get more IRQs and so the machine freeze
almost twice :-)...
Only solution: 
1) get rid of the DAT :-(((
2) upgrade to 2.4.0-test3 or 4 :-)
3) networking with modules. When the spinlock hangs the ethernet you have
the chance to remove the module and restart it again. It works.

with 2.4.0-test3 or 4, the system handles exeptions. It has also a
watchdog when the ethernet hangs !!!!!!!

good luck,

Stefano
