ksymoops'd output of kernel panic (3.15 KB, text/plain)

Description Matt Dainty 2004-04-16 22:24:28 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
When Kudzu is run on bootup to detect any new hardware, it will
reliably segfault, causing a kernel panic, (attached ksymoops'd output).

The problem only seems to trigger on a reboot, booting from cold
appears to work with no problem.

It appears to be caused by my Mitsumi USB 7-in-1 card reader (details
here: http://qbik.ch/usb/devices/showdev.php?id=2223), as when the
problem occurs, /proc/scsi/scsi only lists the devices attached to my
Adaptec 29160 which is probed first before the USB device.

If I remove kudzu from being run on boot, there doesn't appear to be a
problem, all SCSI devices show up on every boot. If I try running
kudzu manually, I can't get it to fail either, it runs and exits normally.

I'm reporting this as a kernel bug as it shouldn't panic in any case.

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

How reproducible:

Steps to Reproduce:
1. Reboot machine
2. Wait for kudzu to run and segfault


Actual Results:  Examine dmesg after boot to find kernel panic,
examine /proc/scsi/scsi to confirm lack of USB SCSI devices

Expected Results:  Nothing obvious, /proc/scsi/scsi should show all
SCSI devices

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
