Description Chris Radek 2012-09-11 17:40:07 UTC
One of the things I tried to get my Airlink101 AWLL5099 (usb wifi)
working was wrapping various related drivers with ndisgen.  This patch
fixes a kernel panic upon loading the resulting .ko file, and eliminates
the warning "no match for InterlockedCompareExchange".

The driver still didn't work, and I have moved on, but google searches
tell me that other drivers may also need this call so I figure the patch
might be helpful.

In my case, the remaining failure is "no match for PoRequestPowerIrp"
and I don't understand that one well enough to fix it.

Fix: Attached patch

Patch attached with submission follows:
How-To-Repeat: Use ndisgen to wrap a windows driver that uses InterlockedCompareExchange.
For example, the one found at:
