(Matt gets CC'd because he's just unlucky :-)
This system is (as always) a pxeboot'd nfsroot'd dual processor box. This time, however, it's running straight GENERIC from the main tree instead of the MAC branch. The box network boots, does a buildkernel -j 8, and then reboots. It currently has no configured swap, suggesting that things broke down when it tried to think about using some swap. Not sure how many loops it took to get to this, but I've seen a couple of different panics that I'll be posting about as they recur. I'm actually trying to track an odd mbuf/nfs interaction...
