Steps to reproduce:
-------------------
This problem can be always reproduced by performing the following steps:
0. Make sure the Intellimouse USB mouse is plugged.
1. Boot into 2.6.0-test9 with "init=/bin/bash"
2. Run "apm -s"
3. Let the system suspend, then resume it from suspension.
4. On the command line, run "rmmod uhci-hcd"
5. The previously described oops will be triggered.

Please, see the attached "config" file for information on the configuration
used to build the kernel.
