You know, I'm constantly amazed just how many ways people find to
mess up a simple thing like sending in a bug report. You went to
so much trouble to emphasize that your system panicked, and you were
dilligent enough to copy down the stack trace.

And then you went and forgot to tell us what the panic message said.

Go back and repeat the crash and make a note of the actual panic
message this time (i.e. "panic: something bad happened!"). Please
note that "I don't remember" or "I'll get around to it later" are
not valid responses.

More than likely this is the result of Andre's recent changes to
the mbuf code. The NDISulator is still working fine for me with 6.x.

When you report the full panic message so that I can tell what
actually went wrong, I may be able to tell you more.
