A gdb stacktrace is much more than "without further details".
It happened inside bcopy.
I asumed that the stacktrace including the sourceline calling bcopy
would be enough.
If you need more then you should say so - I can't guess.

It's a chick egg problem - if software regulary fails then less users
will use such hardware or at least avoid that kind of software.
Don't get me wrong: ipfw is good software which I use daily (on i386)
and I'm happy about the recent features you did, but there are two
sides of the story.
