I just got this panic too, but I am running a July 2 snapshot on this
machine. I was running X when it happened, and the screen didn't update
to show me the debugger, it just showed my frozen desktop. So all I
could do was a boot dump.
On reboot I got:
savecore: reboot after panic: free: duplicated free
savecore: writing core to /var/crash/bsd.0.core
savecore: writing kernel to /var/crash/bsd.0
But when I try to get a trace from the dump I end up with this:
