Options used: -V (default) -o /lib/modules/2.2.10/ (default) -k /proc/ksyms (default) -l /proc/modules (default) -m /usr/src/linux/System.map (default) -c 1 (default)

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.

No modules in ksyms, skipping objects Sep 8 05:30:21 lx01 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000008 Sep 8 05:30:21 lx01 kernel: current->tss.cr3 = 2045c000, %cr3 = 2045c000 Sep 8 05:30:21 lx01 kernel: *pde = 00000000 Sep 8 05:30:21 lx01 kernel: Oops: 0000 Sep 8 05:30:21 lx01 kernel: CPU: 1 Sep 8 05:30:21 lx01 kernel: EIP: 0010:[vc_allocate+182/264] Sep 8 05:30:21 lx01 kernel: EFLAGS: 00010212 Sep 8 05:30:21 lx01 kernel: eax: 01618983 ebx: fc8100a0 ecx: 00000040 edx: 00000014 Sep 8 05:30:21 lx01 kernel: esi: 00000000 edi: 2c313069 ebp: 00000020 esp: df5dbdd8 Sep 8 05:30:21 lx01 kernel: ds: 0018 es: 0018 ss: 0018 Sep 8 05:30:21 lx01 kernel: Process vbda (pid: 6363, process nr: 42, stackpage=df5db000) Sep 8 05:30:21 lx01 kernel: Stack: eb85caee 00000009 c026d990 fc80e000 586260d2 fc80c000 00000080 00000009 Sep 8 05:30:21 lx01 kernel: 00000003 c018c72e c027279c eb85caee eb85caf0 00000002 00000001 df5dbe80 Sep 8 05:30:21 lx01 kernel: 00000004 c018a37d 00000001 eb85caee eb85caf0 00000002 00000000 02224d30 Sep 8 05:30:21 lx01 kernel: Call Trace: [<fc80e000>] [<fc80c000>] [extended_partition+446/548] [ll_rw_block+229/524] [brw_page+700/944] [generic_readpage+127/140] [try_to_read_ahead+271/296] Sep 8 05:30:21 lx01 kernel: Code: 8b 46 08 03 06 39 c7 7c 27 8b 5b 04 85 db 75 1e 57 68 fd aa
