Attached. Currently only from an Nvidia-tainted kernel, though.
If you need it reproduced on an untainted kernel it'll have to
wait until I can reboot the machine.

The Oops location according to gdb is:

(gdb) info line *ipaq_open+0x1cf
Line 656 of "drivers/usb/serial/ipaq.c" starts at address 0x986 <ipaq_open+457>
   and ends at 0x98f <ipaq_open+466>.

The lsusb output of the device:
