Bug 230318

Description of problem:

I get a kernel OOPS in the syslog when inserting an IBM microdrive in
the PCMCIA port of my IBM T30 Labtop.

I the microdrive is available at boot, then the kernel OOPS occaurs, and the
boot is stuck for a couple of minuts, then it continues.

Version-Release number of selected component (if applicable):
2.6.20-1.2949.fc7 and previous 4-5 releases in rawhide.

kernel-2.6.19-1.2914.fc7 works ok.

How reproducible:

Every time

Steps to Reproduce:
1. Bootup Fedora
2. Insert IBM Microdrive in PCMCIA port.
3.
  
Actual results:
Kernel OOPS in syslog


Expected results:
The Microdrive should be auto mounted.

Additional info:

Snip from syslog.
