[OOPS] 2.2.19 USB and Digianswer/Tektronix sniffer

[Dave Airlie]

when boot Linux 2.2.19 with a Digianswer Bluetooth Sniffer plugged into
the USB I get the following oops ... I know the device isn't supported but
I'd like to be able to leave it plugged in without oopsen between
Linux/Windows..

Regards,
	Dave.

ksymoops 0.7c on i686 2.2.19.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.2.19/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
