Ok... I got the machine back up and running (kernel and kernel.old were both botched): grabbed the kernel from ftp://snapshots.jp.freebsd.org/pub/FreeBSD/snapshots/i386/ISO-IMAGES/live-5.2 -CURRENT-20040115-JPSNAP.iso. Below is a comparison between the two. Please let me know what else I can do to help figure this one out. # ident /boot/rescue/kernel > ident.rescue # ident /boot/kernel/kernel > ident.panic # diff -u ident.rescue ident.panic |fgrep "+" |fgrep "FreeBSD" + $FreeBSD: src/sys/cam/scsi/scsi_pt.c,v 1.39 2003/06/10 18:14:05 obrien Exp $ + $FreeBSD: src/sys/cam/scsi/scsi_targ_bh.c,v 1.20 2003/09/30 08:03:52 simokawa Exp $ + $FreeBSD: src/sys/cam/scsi/scsi_target.c,v 1.58 2003/11/09 09:17:20 tanimura Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_cpu.c,v 1.29 2003/12/28 22:15:24 njl Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_ec.c,v 1.42 2004/01/03 02:01:39 njl Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_isab.c,v 1.4 2003/08/24 17:48:01 obrien Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_lid.c,v 1.15 2003/10/25 05:03:24 njl Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_pci.c,v 1.6 2003/09/17 08:32:44 iwasaki Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_pci_link.c,v 1.12 2003/12/23 02:29:46 peter Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_pcib.c,v 1.36 2003/12/18 17:04:11 kan Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_pcib_pci.c,v 1.5 2003/08/24 17:48:01 obrien Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_powerres.c,v 1.16 2003/08/28 16:06:30 njl Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_resource.c,v 1.20 2003/09/26 05:24:55 njl Exp $ + $FreeBSD: src/sys/dev/acpica/acpi_thermal.c,v 1.35 2004/01/12 17:59:10 njl Exp $ + $FreeBSD: src/sys/dev/ata/ata-all.c,v 1.201 2004/01/14 21:26:34 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-queue.c,v 1.16 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-lowlevel.c,v 1.27 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-isa.c,v 1.20 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-pci.c,v 1.74 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-chipset.c,v 1.56 2004/01/14 21:26:34 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-dma.c,v 1.125 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/ata-disk.c,v 1.167 2004/01/14 21:26:34 sos Exp $ + $FreeBSD: src/sys/dev/ata/atapi-cd.c,v 1.160 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/atapi-fd.c,v 1.92 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/atapi-tape.c,v 1.87 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ata/atapi-cam.c,v 1.31 2004/01/14 21:26:35 sos Exp $ + $FreeBSD: src/sys/dev/ppbus/immio.c,v 1.17 2003/08/24 17:54:16 obrien Exp $ + $FreeBSD: src/sys/dev/ppbus/vpo.c,v 1.29 2003/08/24 17:54:16 obrien Exp $ + $FreeBSD: src/sys/dev/ppbus/vpoio.c,v 1.18 2003/08/24 17:54:16 obrien Exp $ + $FreeBSD: src/sys/kern/init_main.c,v 1.239 2004/01/15 10:15:03 des Exp $ + $FreeBSD: src/sys/kern/kern_descrip.c,v 1.221 2004/01/16 08:45:56 des Exp $ + $FreeBSD: src/sys/kern/sched_ule.c,v 1.94 2003/12/20 22:35:20 jeff Exp $ + $FreeBSD: src/sys/kern/sys_pipe.c,v 1.163 2004/01/15 10:15:03 des Exp $ + $FreeBSD: src/sys/kern/uipc_cow.c,v 1.16 2003/11/16 06:11:25 alc Exp $ + $FreeBSD: src/sys/kern/uipc_syscalls.c,v 1.169 2004/01/15 10:15:03 des Exp $ + $FreeBSD: src/sys/kern/uipc_usrreq.c,v 1.114 2004/01/15 10:15:03 des Exp $ + $FreeBSD: src/sys/kern/vfs_syscalls.c,v 1.336 2004/01/15 10:15:04 des Exp $ + $FreeBSD: src/sys/kern/uipc_sem.c,v 1.9 2003/06/11 00:56:58 obrien Exp $ + $FreeBSD: src/sys/i386/acpica/OsdEnvironment.c,v 1.9 2003/08/28 16:26:24 njl Exp $ + $FreeBSD: src/sys/i386/acpica/acpi_machdep.c,v 1.15 2003/11/01 00:18:29 njl Exp $ + $FreeBSD: src/sys/i386/acpica/acpi_wakeup.c,v 1.30 2003/11/03 22:18:57 jhb Exp $ + $FreeBSD: src/sys/i386/acpica/madt.c,v 1.9 2003/12/09 03:04:19 njl Exp $ > > Grabbed new code from cvsup1 this morning (~9am EDT, 16 jan > 04) and am now panicing in a different location: > > FreeBSD/i386 bootstrap loader, Revision 1.1 > (root_at_bsdfs5.gactr.uga.edu, Fri Jan 16 11:10:18 EST 2004) > Loading /boot/defaults/loader.conf /boot/kernel/kernel > text=0x277880 data=0x2a264+0x56838 syms=[0x4+0x36e70+0x4+0x4 > 3c03] /boot/modules/if_fxp.ko text=0x77b4 data=0x1014+0xc > syms=[0x4+0xcf0+0x4+0xdbb] loading required module 'miibus' > /boot/modules/miibus.ko text=0x15820 data=0xc84+0x68 > syms=[0x4+0x1c60+0x4+0x2328 ] /boot/modules/twe.ko > text=0x7398 data=0x5ac+0x8c syms=[0x4+0xdb0+0x4+0xd1d] > Loading /boot/defaults/loader.conf > - > Hit [Enter] to boot immediately, or any other key for command > prompt.
