2940/pre12 problem

  My cow-orker at work always finds some mind-bender works-on-everything-
but-his-machine problem.  ):

  In short, he's seeing a bunch of timeouts that slow him down but don't
seem to be doing any other harm (in the sense that they're not causing
fatal errors to the programs trying to write to disk at that moment).
Mucking with the Adaptec BIOS didn't reveal anything that looked bad
(defaults, except for trying to set Id #0 to 20 MByte/sec during the
test).  He wasn't having this problem with an old redhat installation
running 2.0.34 (presumably without any aic7xxx patches), but now he's
had reason to upgrade and he tripped over this situation.


  I haven't got a chance to rip it apart in person and verify it, but it
is a standard gateway box and probably has a 2940uw card in it.  I had
him try and lock the speed down to 20 MByte/sec & reboot via the adaptec
BIOS, but that obviously isn't being read in or otherwise understood.

  I've enclosed a chunk of syslog output, although looking at the date
tells me that it was taken before we set the speed to 20 MByte/sec.

  What can I do to provide more useful information & help get this fixed?
