So far I couldn't reproduce it, but I think the fact that I couldn't

buildworld/buildkernel lately because of other problems.

Since I'm not much of an expert in the kernel debugger, I tried to let 
it continue with the panic, i.e. typed 'continue' which produced a fatal 
trap 12 right after "Dumping XXXX MB: (~3 values were here)".
