I have rebooted to the old kernel, without debugging. And i still cant replicate the problem when doing a simultaneous make -j4 buildworld and buildkernel. And to top it off, the customer expects the server in production in a few days :P If i can replicate the problem, i will try these patches. FYI The system has frozen previously during normal functions, not when doing compiles, but this seems to be very intermittent.
