Given that the latest lockup (see other email) has lots of locks in the UDP
code, would you like me to try this next ? The kernel which has just locked
is one using Dimtry's patch from
http://www.freebsd.org/cgi/query-pr.cgi?pr=130652
I am not sure why that would give me different traces during the lockup
though. I was doing a lot more TCP traffic this time, but that shouldnt
interfere with UDP should it ?
