[-- Attachment #1 --] I do not believe this panic is hardware related as I am currently composing this letter on the same system (I had a backup of my working kernel) Current Working Kernel: FreeBSD kkuehl-fbsd.cisco.com 4.7-RC FreeBSD 4.7-RC #5: Fri Oct 4 09:51:47 PDT 2002 root@kkuehl-fbsd.cisco.com:/usr/obj/usr/src/sys/ELITE i386 This IBM T30 Thinkpad has been running freebsd-stable happily for approximately two months with the same kernel config. (I have attached a diff between my kernel config and GENERIC) After cvsuping on 10/11/2002, building and installing world and building and installing kernel and mergemastering I get an immediate kernel panic. I then enabled the following in hopes of captureing a backtrace: Line from /etc/fstab showing swap partition: /dev/ad0s1b none swap sw 0 0 Line from /etc/rc.conf enabling dumpdev: dumpdev="/dev/ad0s1b" Relevant lines from /usr/src/sys/i386/conf/MYKERNEL: options DDB, DDB_UNATTENDED makeoptions DEBUG=-g Unfortunately, the kernel panics/reboots (a second time) before it copies the core from swap to /var/crash. Am I missing a step in obtaining a core / dump? Is there another approach? I realize that this report is unhelpful without a backtrace. Thanks in advance, Kirby Kuehl [-- Attachment #2 --] --- GENERIC Sat Aug 31 13:28:26 2002 +++ ELITE Fri Oct 11 07:29:04 2002 @@ -1,4 +1,4 @@ -# + # GENERIC -- Generic kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on @@ -18,18 +18,18 @@ # $FreeBSD: src/sys/i386/conf/GENERIC,v 1.246.2.48 2002/08/31 20:28:26 obrien Exp $ machine i386 -cpu I386_CPU -cpu I486_CPU -cpu I586_CPU +#cpu I386_CPU +#cpu I486_CPU +#cpu I586_CPU cpu I686_CPU -ident GENERIC +ident ELITE maxusers 0 -#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols - -options MATH_EMULATE #Support for x87 emulation +options DDB, DDB_UNATTENDED +makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols +#options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking -options INET6 #IPv6 communications protocols +#options INET6 #IPv6 communications protocols options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options SOFTUPDATES #Enable FFS soft updates support @@ -54,6 +54,7 @@ options P1003_1B #Posix P1003_1B real-time extensions options _KPOSIX_PRIORITY_SCHEDULING options ICMP_BANDLIM #Rate limit bad replies +options TCP_DROP_SYNFIN options KBD_INSTALL_CDEV # install a CDEV entry in /dev options AHC_REG_PRETTY_PRINT # Print register bitfields in debug # output.
