Description Robert Theisen 2004-04-08 19:36:04 UTC
Description of problem:
Plugging in a konica KD-400Z digital camera (via USB) while the system
is running will result in a kernel panic after approximately 10 seconds.

Version-Release number of selected component (if applicable):
kernel-2.4.21-9.0.1.EL  (i686)

How reproducible:

Steps to Reproduce:
1.Boot Machine Normally
2.Plug in camera via USB
3.Wait 10-20 seconds
Actual results:
Kernel panics and machine freezes

Expected results:
/dev/sda is abstracted from the usb device and made available as a
mountable device.

Additional info:
Stack trace and panic info will be attached

What I can get from the trace that has not yet scrolled off screen is
as follows.

Comment 2 Pete Zaitcev 2004-04-19 18:22:14 UTC
Please try 2.4.21-12.EL. If you cannot find it, use the one from:

Comment 3 Robert Theisen 2004-05-03 17:56:13 UTC
The kernel referenced above will not boot.  

Stops after the message

"Total HugeTLB memory allocated, 0"

Do you have a non-smp version I could try?

Comment 4 Robert Theisen 2004-05-03 17:57:23 UTC
I will need the kernel-source rpm as well to rebuild the vpnclient
packages if this kernel fixes the usb problem.

Thank You

Comment 5 Pete Zaitcev 2004-08-20 07:26:47 UTC
There's non-SMP kernel at the above location now, as well as
kernel-source rpm. Robert, please test 2.4.21-17.EL.
