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?
