This is a followup to my earlier, quick message - the machine finally stayed up. (After several weeks of no problems, the machine went down on a kernel panic. It rebooted fine, went through the full boot sequence, printed the login prompt to the console,and immediately rebooted. The boot sequence completed, at which time the machine rebooted itself. This happened ~20 times.) (running FreeBSD 2.1.5-RELEASE #0 - the second, good release, P100, IDE, 16M, kernel.GENERIC) After the initial kernel panic, the machine rebooted itself immediately after completing the boot sequence. I power-cycled the machine, etc and saw the same behavior ~20 times. How can I get a better idea of what caused the initial panic? Or of what could have caused the machine to automatically reboot? Many thanks Thor Clark thor@tabula.com This is initial panic: Aug 13 11:25:37 trex /kernel: sio1: 165 more tty-level buffer overflows (total 2667) Aug 13 11:25:44 trex /kernel: sio1: 267 more tty-level buffer overflows (total 2934) Aug 13 12:41:17 trex /kernel: kernel page directory invalid pdir=0x0, va=0xefc20000 Aug 13 12:41:17 trex /kernel: panic: invalid kernel page directory Aug 13 12:41:17 trex /kernel: Aug 13 12:41:17 trex /kernel: syncing disks... 10 10 5 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 <3>sio1: 588 more tty-level buffer overflows (total 3522) Aug 13 12:41:17 trex /kernel: 1 1 <3>sio1: 297 more tty-level buffer overflows (total 3819) Aug 13 12:41:17 trex /kernel: FreeBSD 2.1.5-RELEASE #0: Sun Jul 21 16:12:25 PDT 1996 then after the boot sequence: (this recurred about 20 times, with exactly the same messages) Aug 13 12:42:21 trex /kernel: npx0 on motherboard Aug 13 12:42:21 trex /kernel: npx0: INT 16 interface Aug 13 12:42:13 trex named[68]: starting. named LOCAL-960717.011537 Wed Jul 17 01:15:37 1996 xxx@xxxxxxx.xxxxx.com:/usr/src/usr.sbin/named Aug 13 12:42:14 trex named[69]: Ready to answer queries.
