Hi all, New to FBSD, and in the process of moving my Linux/Windows PC to FBSD/Windows. I got two spontaneous reboots last night (the first times it happened) and I got fatal trap 12s in /var/log/messages each time. I wasn't doing anything too heavy, just a make index && make readmes on my ports, listening to some music through XMMS and browsing the web via Mozilla. I searched the archives and the FAQ. I haven't built a debugging kernel yet, but I thought I would post the info I have in the hopes that someone might be able to help. I did do an nm - n on the kernel, however. uname -a: FreeBSD creadle.oc.cox.net 4.8-RELEASE-p13 FreeBSD 4.8-RELEASE-p13 #4: Wed Oct 15 08:55:21 PDT 2003 chris@creadle.oc.cox.net:/usr/obj/usr/src/sys/CREADLE i386 /var/log/messages: Oct 14 21:45:23 creadle /kernel: Fatal trap 12: page fault while in kernel mode Oct 14 21:45:23 creadle /kernel: fault virtual address = 0xbfca02c8 Oct 14 21:45:23 creadle /kernel: fault code = supervisor read, page not present Oct 14 21:45:23 creadle /kernel: instruction pointer = 0x8:0xc028fe83 Oct 14 21:45:23 creadle /kernel: stack pointer = 0x10:0xd2cfbcf8 Oct 14 21:45:23 creadle /kernel: frame pointer = 0x10:0xd2cfbd08 Oct 14 21:45:23 creadle /kernel: code segment = base 0x0, limit 0xfffff, type 0x1b Oct 14 21:45:23 creadle /kernel: = DPL 0, pres 1, def32 1, gran 1 Oct 14 21:45:23 creadle /kernel: processor eflags = interrupt enabled, resume, IOPL = 0 Oct 14 21:45:23 creadle /kernel: current process = 73961 (sh) Oct 14 21:45:23 creadle /kernel: interrupt mask = net tty bio cam Oct 14 21:45:23 creadle /kernel: trap number = 12 Oct 14 21:45:23 creadle /kernel: panic: page fault nm -n: creadle# nm -n /kernel | grep c028fe8 c028fe88 T pmap_ts_referenced creadle# nm -n /kernel | grep c028fe c028fe7c T pmap_phys_address c028fe88 T pmap_ts_referenced I did two because I thought it was odd that the first one came up with a higher address than the actual pointer. Any good suggestions? chris __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com
