I hope this is the right place to report a problem like this. Or should
I have filed a pr?
I'm still getting a panic in 3.3-RC code as of last night.
Like I said in my last message, this happens with almost every buildworld
on a FreeBSD box which is doing some light NFS serving, very light
DNS, ppp -nat, and a very light squid proxy.
Here is a trace from gdb -k. And below is my dmesg and then my kernel
config. And I would be more than happy to provide more info or help
in any way in which my non-coding carcas can.
