ksymoops 2.4.8 on i686 2.5.56. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.56/ (default) -m /boot/System.map-2.5.56 (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. Error (regular_file): read_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod Call Trace: [] [] [] [] [] [] [] [] Unable to handle kernel NULL pointer dereference at virtual address 0000006c c0280249 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0060:[] Tainted: P Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010216 eax: ffffffff ebx: dc4cff34 ecx: 0000000f edx: 0000006c esi: 0000006c edi: dc4cff34 ebp: 00000010 esp: dc4cfef4 ds: 007b es: 007b ss: 0068 Stack: dc4ce000 00000001 00008913 dc4cff34 c02802e1 dc4cff34 dc4cff34 00000001 c02805a3 dc4cff34 dc4ce000 c0282209 dc4cff34 bffff140 00000020 00000000 30707070 08148d00 bffff168 0060de02 406962fc bffff1a0 00000089 00000012 Call Trace: [] [] [] [] [] [] [] Code: ac ae 75 08 84 c0 75 f5 31 c0 eb 04 19 c0 0c 01 85 c0 74 07 Trace; c01ba298 Trace; c02825cb Trace; c01f9f45 Trace; c01f7c5c Trace; c01f7b33 Trace; c015ba70 Trace; c015c681 Trace; c010951b >>EIP; c0280249 <__dev_get_by_name+29/50> <===== Trace; c02802e1 Trace; c02805a3 Trace; c0282209 Trace; c02bb8e6 Trace; c0279315 Trace; c015c681 Trace; c010951b Code; c0280249 <__dev_get_by_name+29/50> 00000000 <_EIP>: Code; c0280249 <__dev_get_by_name+29/50> <===== 0: ac lods %ds:(%esi),%al <===== Code; c028024a <__dev_get_by_name+2a/50> 1: ae scas %es:(%edi),%al Code; c028024b <__dev_get_by_name+2b/50> 2: 75 08 jne c <_EIP+0xc> Code; c028024d <__dev_get_by_name+2d/50> 4: 84 c0 test %al,%al Code; c028024f <__dev_get_by_name+2f/50> 6: 75 f5 jne fffffffd <_EIP+0xfffffffd> Code; c0280251 <__dev_get_by_name+31/50> 8: 31 c0 xor %eax,%eax Code; c0280253 <__dev_get_by_name+33/50> a: eb 04 jmp 10 <_EIP+0x10> Code; c0280255 <__dev_get_by_name+35/50> c: 19 c0 sbb %eax,%eax Code; c0280257 <__dev_get_by_name+37/50> e: 0c 01 or $0x1,%al Code; c0280259 <__dev_get_by_name+39/50> 10: 85 c0 test %eax,%eax Code; c028025b <__dev_get_by_name+3b/50> 12: 74 07 je 1b <_EIP+0x1b> 1 warning and 1 error issued.
