Hi,

	Been having occasional reboots after wiping my machine clean and
starting over. So I enabled savecore and tried to figure what happened.
Followed the instructions at http://www.lemis.com/texts/panic.txt 
(The 2 WITNESS statements aren't valid it seems) and when I did, my system
would panic every 15 minutes!

Apr  7 23:04:29 himinbjorg savecore: reboot after panic: pmap_page_protect: ille
gal for unmanaged page, va: 0xe8112000
Apr  7 23:04:29 himinbjorg /kernel: Apr  7 23:04:29 himinbjorg savecore: reboot 
after panic: pmap_page_protect: illegal for unmanaged page, va: 0xe8112000

	Previously it panic'd just the once (That I caught) with :

Apr  6 13:44:53 himinbjorg savecore: reboot after panic: page fault
Apr  6 13:44:53 himinbjorg /kernel: Apr  6 13:44:53 himinbjorg savecore: reboot 
after panic: page fault


	Is there something in those instructions that aren't right? I used :

makeoptions     DEBUG=-g                #Build kernel with gdb(1) debug symbols

	I already had :

options         DDB


	And added :

options         BREAK_TO_DEBUGGER
options         KTRACE
options         DIAGNOSTIC
options         INVARIANTS
options         INVARIANT_SUPPORT

	Have I tickeled something?
