by Hi All,
I have an Adaptec 19160B Ultra160 SCSI controller with a
QUANTUM ATLAS10K3_36_WLS disk. Running Mandrake Linux 8.2
with its default kernel 2.4.18-6mdk. The system auto-detected
the controller and installed the AIC7XXX driver for it.
It works most of the time, however I do get some problems
time-to-time (typically when there is a heavy load on the
disk, e.g. copy/read/write some large files). In these
cases the whole system "hangs" for a minute or two, then
I see in the /var/log/messages file the following kind of
lines:

Sometimes the system comes back and all the files seem OK, but other
cases some files get corrupted.
Any idea what could be the problem ?
Is it a faulty disk, faulty controller or some setup problem?
Any suggestions would be greatly appreciated!
Thanks,
Zsolt
