All disk-partitions contains ext3 with the following mount options: /dev/ide/host0/bus0/target0/lun0/part1 on / type ext3 (rw,errors=remount-ro) proc on /proc type proc (rw) /dev/ide/host0/bus0/target0/lun0/part3 on /home type ext3 (rw) /dev/ide/host0/bus0/target0/lun0/part4 on /var type ext3 (rw) The crash seems to be related to a mail loop, the MTA running on the box is postfix. The box has a single processor. The kernel is patched with the following patches: - netfilter submitted patches (those submitted at 2.4.22pre7) - our tproxy patch (version #18) - freeswan - the AIC7xxx driver from people.freebsd.org (it is not used in the box) - 2.4.21-ac4 ----- Forwarded message from Major Csaba ----- From: Major Csaba To: bazsi@balabit.hu Subject: oops Date: Tue, 29 Jul 2003 10:18:13 +0200 Unable to handle kernel NULL pointer dereference at virtual address 00000000 c0125e4e *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 00000000 ebx: c1070390 ecx: 010000c4 edx: c1070390 esi: 00000000 edi: 00000000 ebp: c2699184 esp: c2215f10 ds: 0018 es: 0018 ss: 0018 Process smtp (pid: 13916, stackpage=c2215000) Stack: 00000000 c2215f48 00000000 c2699184 00000000 00000000 00000001 c2215f48 00000000 c0125fdb c26990c0 c397a800 c0257e80 c0798620 00000000 c01464e6 c2699184 00000000 00000000 c0798620 c26990c0 c10b5420 c0144166 c26990c0 Call Trace: [] [] [] [] [] [] [] Code: 89 28 eb 0d 8b 03 89 68 04 89 45 00 89 5d 04 89 2b c7 44 24 >>EIP; c0125e4e <===== >>ebx; c1070390 <_end+d94f9c/4548c0c> >>ecx; 010000c4 Before first symbol >>edx; c1070390 <_end+d94f9c/4548c0c> >>ebp; c2699184 <_end+23bdd90/4548c0c> >>esp; c2215f10 <_end+1f3ab1c/4548c0c> Trace; c0125fdb Trace; c01464e6 Trace; c0144166 Trace; c0134744 Trace; c0133755 Trace; c01337a3 Trace; c0108783 Code; c0125e4e 00000000 <_EIP>: Code; c0125e4e <===== 0: 89 28 mov %ebp,(%eax) <===== Code; c0125e50 2: eb 0d jmp 11 <_EIP+0x11> c0125e5f Code; c0125e52 4: 8b 03 mov (%ebx),%eax Code; c0125e54 6: 89 68 04 mov %ebp,0x4(%eax) Code; c0125e57 9: 89 45 00 mov %eax,0x0(%ebp) Code; c0125e5a c: 89 5d 04 mov %ebx,0x4(%ebp) Code; c0125e5d f: 89 2b mov %ebp,(%ebx) Code; c0125e5f 11: c7 44 24 00 00 00 00 movl $0x0,0x0(%esp,1) Code; c0125e66 18: 00 2 warnings issued.
