I just got the same thing doing a make -j8 world
Machine is a dual pentium pro Intel PR440FX
This must be from the recent vm changes as I could make -j8 world
continually a
few days ago without problem. This is the second time it happened to me
the first time I was running X so I couldn't see the debugger message .
This time without X I got the :
panic: found dirty cache page
