Description of problem:
While doing backup with Legato Networker (RedHat machine is client) kernel
panics in qlogicisp driver. Similar problem is also reported in
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run savegrp (Legato backup command).
Computer is Compaq 2xP1133MHz system with 2GB of RAM. Root file system in on
another controller (Compaq CISS). Kernel is from rpm: kernel-smp-2.4.9-21.
Installed RHES3 into this computer and bug reappeared because mod_isp
driver is gone. qlogicisp module Oopses again after some load.
Could you please provide the RHEL3 kernel version and the console oops output?
"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 This driver is no longer
maintained by the author and is not in RHEL 3.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 It is also no longer
maintained by the vendor.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.
