All, I can confirm that I've had numerous crashes that seem to be network related using 5.4R AMD64 on a dual AMD Tyan S2882 Thunder K8S PRO. Removing the Berkley Packet Filter and IPFilter from the kernel reduced the frequency of the crashes. Moving from the onboard bge to the onboard fxp interface didn't seem to make much difference. Running the GENERIC uniprocessor kernel seemed to eliminate the problems. I got conformation that there seems to be locking issues with the multi threaded implementation of the network stack from Gleb Smirnoff (glebius@freebsd.org). Gleb suggested setting "debug.mpsafenet=0" to turn off multi-threaded networking (as far as I understand): http://lists.freebsd.org/pipermail/freebsd-current/2004-August/035253.html This initially looked like it fixed the problem, but my system crashed again a day later.
