Palm Pilot causing FC5 Core dump

[ag65151]

The actual core dump follows. Here is the relevant info:

kernel: 2.6.16-1.2080_FC5
pilot-link: 0.11.8
Palm is Kyocera7135 smart phone attached via cradle to USB.

This dump occured after a successful list from pilot-xfer -l

The system locked up, the cpu maxed out and then this dumped on my console. Apparently it is an issue with detaching the USB device when HotSync is complete.

I have looked for solutions, but found none. I am relatively new to Linux, so please speak slowly :)

This is my only problem with FC5. Everything else works great!
