Comment 1 Mindaugas Riauba 2004-10-27 12:54:44 UTC

  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 22:11:39 UTC

Could you please provide the RHEL3 kernel version and the console oops output?

Comment 3 Tom Coughlan 2004-11-15 23:06:18 UTC

"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 This driver is no longer
maintained by the author and is not in RHEL 3.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 It is also no longer
maintained by the vendor.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.
