[1.] One line summary of the problem:
Non-fatal OOPS in 2.4.19-rc1 USB visor/usb-serial/usb-uhci usb_unlink_urb
[2.] Full description of the problem/report:
While running a sync to my visor, I got the attached OOPS. Judging by the
oops, it happened during jpilot, which I ran after having run pilot-xfer.
[3.] Keywords (i.e., modules, networking, kernel):
USB usb-serial usb-uhci visor
[4.] Kernel version (from /proc/version):
Linux version 2.4.19-rc1 (fortytwo@manetheren) (gcc version 2.95.4 20011002 (Debian
prerelease)) #6 Mon Jun 24 16:38:47 PDT 2002
This is vanilla 2.4.19-rc1.
[5.] Output of Oops.. message (if applicable) with symbolic information

Since this is non-fatal, I haven't tried to reproduce it, let alone try
other kernels.
