Hello,
  Just a small followup here, I haven't had a chance to dig throught the
driver
yet, I did forward a copy to the aic7xxx maintainer, but no response
yet. However
if you are having problems on an intel platform that is good news. (Non
intel
platforms get blown off a lot sigh.) This weekend I will try to debug it
or at least
figure out something. My initial guess is to disable all command tag
queueing, 
  While I am in the code I also want to go digging around and see if I
can find a 
way to turn of the in memory buffering that Linux does for block devices
as this
would make my fscking a LOT shorter, (18 gigs is slow),
   But first I need to find my null modem serial cable. sigh. funnsies.
