Subject: kern/140338: FreeBSD 8.0 RC2 with vm.pmap.pg_ps_enabled=1 kernel
panic with makeworld
Date: Thu, 12 Nov 2009 20:09:36 +0100
Update:
Following proposals on the list freebsd-current today I set
hw.mca.enabled="1" and vm.pmap.pg_ps_enabled="1" in /boot/loader.conf
on my (under load) spontaneously rebooting opteron proliant server.
The server was upgraded to FREEBSD-8.0-PRERELEASE today (Nov. 12th 2009)
This is what happened..
