Hi list,

I can confirm I've seen the same problem. After upgrading from 7-stable
to 8.0-RC2 my machine just reboots during 'make buildworld' without
diagnostics. But switching vm.pmap.pg_ps_enabled on/off does not
work for me. My machine reboots every time I try to build world.
I don't think I have a hardware problem: under 7-stable I can build
world/kernel for both 7-stable and 8.0-RC2 without problems.
