None that looked like they were attributable to WinPcap or McAfee. Of
course that isn't foolproof (it's easy for a buffer overflow to mess up
a totally different driver in kernel mode), but the few blue-screens we
have seen were limited to machines that had an older driver installed to
handle hardware from National Instruments. (Of course the crash only
happened when a user logged off without manually shutting down the
program that had a connection to the driver open, so the "clean" close
couldn't happen. I suspect the driver wasn't properly handling the
events that signal a surprise close.)
I've also seen WinPcap blue-screens on a *really* old driver version
(3.1? maybe even 3.0) when a user program makes a DeviceIoControl
request after the wireless card is disabled. This has nothing to do
with McAfee, though, and 4.x fixes that issue as well.
Of course, we're using McAfee 8.5, centrally-managed. The home user
version, or other newer product versions, might have all kinds of extra
junk turned on that may also be interfering, I don't know...
