Oops in 2.5.69 during 'modprobe uhci-hcd'

Oops in 2.5.69 during 'modprobe uhci-hcd'

[Eric Buddington]

linux-2.5.69, mostly modular, no third-party drivers
external NEC IDE CD-RW in an USB-IDE converter case
SurfBoard USB Cable modem
USB Controller: VIA Technologies, Inc. USB (rev 128)
USB Controller: VIA Technologies, Inc. USB 2.0 (rev 130)
Athlon XP 2000+ CPU

After burning a CD at 16x with no problems using the ehci-hcd driver,
I ran 'modprobe uhci-hcd' and got the following oops. Hope this is of
interest.
