Hi folks!

There always have been problems with the SCSI subsystem of my server (dual
PIII 450) since I upgraded to 2.4. Exchanging the disk didn't help. I get
errors from SCSI about once a week, last time the disks were unaccessable
(sysrq-sync/umount printed on the console, but didn't touch the disks).
This time I was lucky enough to capture the error message, but I am not
skilled enough to decode its meaning:

The upper layer (scp to a reiserfs partition) apparently didn't see an
error, but this I don't know for sure. Here's the output of
/proc/scsi/aic7xxx/1:

The other IDs are unused.

Now my question? What actually did happen to cause this error? Is it
hardware-related? _May_ it be caused by faulty RAM? Could this go away by
switching to aic7xxx_old or another version of aic7xxx?

Kernel is 2.4.6 vanilla, compiled with gcc3.0.1.

Thanks for your answers,
					Roland

 Hello
 From kernel 2.6.0, I've a problem with the aic7xxx driver (2.6.0-testXX was
ok).
 Until 2.6.7 I can solve this issue deleting the original aic7xxx directory
in the kernel source and substitute this with the one downloaded from
http://people.freebsd.org/~gibbs/linux/ !
 From 2.6.7 I can't do this anymore, because I get some error compiling the
kernel!
 Can some one tell me if there is a solution, now I'm stuck with 2.6.7 and
can't upgrade my kernel!
 
 The only thing that I've noticed is the ACPI row before the detection of
the aic7xxx, in the 2.6.X (where X>7) it could be an ACPI problem??
 
 Thanks in advance
 
 Bye bye
