Re: Stack backtrace

It seems I jumped the gun on having tcp backtrace fixed. Heres what I'm
seeing now. Also when using nfs or probably any high speed networking it
makes the console scroll with this stuff.

This is freshly rebuilt using generic kernel configuration. Not using a
make.conf. Fresh buildworld and installworld. Heres small part of my dmesg
so you know what sys I have.
