>Description:
If I ndisgen w70n51.* and then load it, kldload gets stuck in ndissp. If I open
another terminal and do ifconfig ndis0 up I get a panic - I can only hand
transcribe it as kgdb doesn't appear to generate a valid backtrace :(

ndis0: NDIS ERROR: c000138d

fatal trap 12: page fault while in kernel mode

Obviously this is a bit suboptimal - I'll take a photo next time :)

>How-To-Repeat:
mkdir /tmp/ndis
cd /tmp/ndis
fetch ftp://ftp.dell.com/network/R86279.EXE
unzip -j R86279.EXE Drivers/w70n51.sys Drivers/w70n501.inf
ndisgen
kldload ./w70n51_sys.ko &
ifconfig ndis0 up

I can provide a serial console to the system for testing purposes if necessary.
