Hi,
I am experiencing odd error messages on a server and can't sort out if
it is a software or hardware problem.
Server is running linux 2.6.22 kernel from Ubuntu server distro
(2.6.22-14-server) on a bi-AMD64 Opteron machine.
The SCSI board is listed as follows by lspci :

First SCSI chain has 4 Ultra320 harddrives, and second one (scsi5) has 4
Ultra320 harddrives and a 160 tape reader.
Regularely, we have a bunch of such errors in /var/log/messages (every
10 minutes or so, when the machine is active, plus a detailed card
dump) :

But yesterday, we had a worse problem, where half our disks went
offline, with the following log (one card dump for each of the four
disks).
SO, any tip on what might be going wrong ??
Thanks in advance,
Franck
