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: Always 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: Hardware: 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.
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.
