> Same backtrace as reported here?
I'm unable to get the new backtrace, but judging from what I can see
on the console pre-reboot, it's exactly the same deal since
8.0-RELEASE - panic with dummynet as main star.

I'm not sure anymore that em is at fault here. Anyway, currently I'm
running FreeBSD 8.2-PRERELEASE #1: Fri Jan  7 17:19:28. If something
happened since then that could fix this, I'll gladly update.
