Similar problem is also reported in http://www.cs.helsinki.fi/linux/linux-kernel/2001-47/0820.html Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Run savegrp (Legato backup command). 2. 3. Additional info: Computer is Compaq 2xP1133MHz system with 2GB of RAM. Root file system in on another controller (Compaq CISS).

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 This driver is no longer maintained by the author and is not in RHEL 3.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 It is also no longer maintained by the vendor.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