Hello,
this morning our server crashed without any log messages, nothing captured via
serial cable and magic sysrqs also didn't work.
Anyway during the reboot on oops of the aic79xx module occured, see below .
This is a 2.6.11.12 kernel, patched with bluesmoke and the bio-clone fix.
Furthermore, the drbd module is loaded. You may find a dmesg, lsmod and lspci
information and the kernel config here:

Even though there was an oops, the aic79xx module and the card still seem to
work, we currently uncertain if we better should reboot again and/or try to
use a newer kernel or can leave the system as it is without another reboot.
Of course, we would also like to know the reason for the oops. Any help is
appreciated.
Thanks in advance,
Bernd
