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):
Steps to Reproduce:
1. Upgrade from 2.4.18-14 to 2.4.19-17.8.0 (via rhn)
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 ;-)
AMD 2200+ XP
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.
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.
