Happened when reading a probably damaged CD, don't know if that is related (didn't look so in the backtrace). System is FreeBSD klamath.ankon.de.eu.org 6.0-CURRENT FreeBSD 6.0-CURRENT #16: Sun Sep 5 12:18:47 CEST 2004 =20 root@klamath.ankon.de.eu.org:/usr/obj/usr/src/sys/KLAMATH i386, sources from around ~0900. Kernel config contains IPV6, IPSEC (so no mpsafenet), ULE, and the default setting for PREEMPTION (i didn't set any), no WITNESS or INVARIANTS, but makeoptions DEBUG=3D-g. Here it is: ----- Fatal trap 12: page fault while in kernel mode fault virtual address =3D 0x1 fault code =3D supervisor write, page not present instruction pointer =3D 0x8:0xc05e5f12 stack pointer =3D 0x10:0xcbf1dc0c frame pointer =3D 0x10:0xcbf1dc28 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 27 (swi5: clock sio) trap number =3D 12 panic: page fault (kgdb) bt full #0 doadump () at pcpu.h:159 No locals. #1 0xc051b576 in boot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:385 first_buf_printf =3D 1 #2 0xc051bcf7 in panic (fmt=3D0xc0708284 "%s") at /usr/src/sys/kern/kern_shutdown.c:541 bootopt =3D 260 newpanic =3D 0 buf =3D "page fault", '\0' #3 0xc06de456 in trap_fatal (frame=3D0xcbf1dbcc, eva=3D1) at /usr/src/sys/i386/i386/trap.c:809 code =3D 16 type =3D 12 ss =3D 16 esp =3D 0 softseg =3D {ssd_base =3D 0, ssd_limit =3D 1048575, ssd_type =3D 27= ,=20 ssd_dpl =3D 0, ssd_p =3D 1, ssd_xx =3D 4, ssd_xx1 =3D 1, ssd_def32 =3D 1, ssd_gran =3D 1} #4 0xc06de6fb in trap_pfault (frame=3D0xcbf1dbcc, usermode=3D0, eva=3D1) at /usr/src/sys/i386/i386/trap.c:727 va =3D 0 vm =3D (struct vmspace *) 0x0 map =3D 0xc076cb20 rv =3D 1 ---Type to continue, or q to quit--- ftype =3D 1 '\001' p =3D (struct proc *) 0x0 #5 0xc06deaf5 in trap (frame=3D {tf_fs =3D 24, tf_es =3D 16, tf_ds =3D 16, tf_edi =3D -1042350080, tf= _esi =3D -1, tf_ebp =3D -873341912, tf_isp =3D -873341960, tf_ebx =3D -104235008= 0, tf_edx =3D -1043508736, tf_ecx =3D -1042350080, tf_eax =3D 1, tf_trapno =3D= 12, tf_err =3D 2, tf_eip =3D -1067557102, tf_cs =3D 8, tf_eflags =3D 66182, tf_= esp =3D 4, tf_ss =3D 582}) at /usr/src/sys/i386/i386/trap.c:417 p =3D (struct proc *) 0xc1901540 sticks =3D 3421625312 i =3D 0 ucode =3D 0 type =3D 12 code =3D 2 eva =3D 1 #6 0xc06d019a in calltrap () at /usr/src/sys/i386/i386/exception.s:140 No locals. #7 0x00000018 in ??
