Description Jez Tucker 2002-11-10 12:17:29 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830

Description of problem:
When registering the USB / Firewire device (it's the ohci1394 driver), the
system locks up, oops's and dumps the kernel state. FYI: the caps lock and
scroll lock also flash repeatedly.

This doesn't happen with the stock RH 8.0 kernel (2.4.18-14)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Upgrade from 2.4.18-14 to 2.4.19-17.8.0 (via rhn)
2. Reboot
3. Allow machine to boot 

Actual Results:  Kernel oops and dumped info to /var/log/ksyms.<n>
Machine was unusable.
Required hard reset.

Expected Results:  Well, the machine should have booted alike kernel 2.4.18-14 ;-)

Additional info:

AMD 2200+ XP
512MB PC2700
Gigabyte GA-7VAXP (via KT400 chipset)
Onboard USB 2.0, 1.0, Firewire (all configured 'on' in BIOS)
PCI QLogic SCSI (ISP1020 driver)

Installed RH 8.0 as W/S.

See URL for in depth info.

Comment 1 Jez Tucker 2002-12-24 10:33:46 UTC
Made incorrect diagnosis.

Problem actually occurs slightly before.

Actual problem is failure to insmod qlogicisp module, resulting in kernel dump.

Occurs on any kernel released later than 2.4.18-14

Can be reproduced on multiple machines with different hardware and different 
(but identical model) qlogic isp 1020 scsi cards.

Will create new bug report concerning above issue.
