  Installed RHES3 into this computer and bug reappeared because mod_isp 
driver is gone. qlogicisp module Oopses again after some load.
Comment 2 Ernie Petrides 2004-11-15 17:11:39 EST
Could you please provide the RHEL3 kernel version and the console oops output?
Comment 3 Tom Coughlan 2004-11-15 18:06:18 EST
"isp_mod" is the "Feral" QLogic driver. This driver is no longer
maintained by the author and is not in RHEL 3.

The qlogicisp driver is a possible substitute. It is also no longer
maintained by the vendor. It is not supported by Red Hat, but we
include it kernel-unsupported-2.4.21-<version>.rpm, if you want to use it.

I would call your attention to the following in scsi/README.qlogicisp: 

This driver works well in practice, but does not support disconnect/
reconnect, which makes using it with tape drives impractical.
