Description IBM Bug Proxy 2003-05-28 14:52:25 EDT

Please fill in each of the sections below.

Hardware Environment:
Dual processor SMP pentium III 1Ghz
Adaptec 39320D HBA version 4.00.0 firmware

Software Environment:
Redhat Enterprise version 3 alpha 3 (and 2)
aic79xx version 1.3.0 for alpha 3 and 1.3.4 for alpha 2
(aparently downgraded)

Steps to Reproduce:
1.modprobe aic79xx
2.rmmod aic79xx
3.

Actual Results:
Random, usually locking up of the system, behavior consistant with resource
corruption.  The module is removed, and sometimes is able to be reinstalled. 
When this happens there's no indication that there's any issues, the attached
peripherals work and don't seem to have any contention issues.

Expected Results:
Module removed with the system remaining functional.

Additional Information:
It is not necessary to attach any devices to the SCSI chain, it is sufficient to
just install and remove the module.

Comment 1 IBM Bug Proxy 2003-06-19 11:32:07 EDT

Any update on this?

Comment 2 Bill Nottingham 2003-07-24 01:24:47 EDT

Bug was filed against both the wrong product and wrong component. Fixing.

Comment 3 Tom Coughlan 2003-07-24 11:33:47 EDT

The aic79xx driver is updated to rev. 1.3.10 in Taroon B1. (This driver is still
fairly new and has undergone quite a bit of change recently.)  Please try the B1
kernel and let us know if this problem is fixed.

------ Additional Comments From denebeim@us.ibm.com  2003-04-08 16:44 -------
I've tested the 1.3.10 version that is in Taroon B1 and it seems to have fixed
the problem.  Good job, thanks.

Closing out on own experience as well as confirmation from original reporter.
