Description Mads Kiilerich 2008-03-10 12:54:53 UTC

Description of problem:

When I remove and insert my "speed link" usb sound card I get dmesg stacktrace.
The troubles might start with "sysfs: duplicate filename 'card1' can not be created"

(The soundcard didn't work anyway - I'm trying to find out what is going on...)


Version-Release number of selected component (if applicable):
kernel-2.6.24.3-12.fc8

How reproducible:
100% on 2.6.24 - haven't seen it before.

Steps to Reproduce:
1.

3.
  
Actual results:
