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?
