SubjectReproducible SCSI Error with Adaptec 7902
I am receiving the following messages in my system log when stress testing
with Cerberus (http://sourceforge.net/projects/va-ctcs). This is with an
onboard Adaptec 7902 Ultra 320 SCSI adapter. The messages are reproducible
on two different systems. This is with the 1.1.0 aic79xx driver, on
both the
stock Redhat kernel, and with a kernel compiled from the 2.4.19 sources.
The
system does not seem to be harmed by the messages, but I would like to
know if
they point to a problem or not. Interestingly, if I put and Adaptec
29320 PCI
card into the same machine, and use the same driver, the error is not
reproducible.

Mike
