Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.3.99-pre8/ (default) -m /usr/src/linux/System.map (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.
Warning (compare_ksyms_lsmod): module isa-pnp is in lsmod but not in ksyms, probably no symbols exported e820: 0009fc00 @ 00000000 (usable) e820: 00000400 @ 0009fc00 (reserved) e820: 00010000 @ 000f0000 (reserved) e820: 07efd000 @ 00100000 (usable) e820: 00002000 @ 07ffd000 (ACPI data) e820: 00001000 @ 07fff000 (ACPI NVS) e820: 00010000 @ ffff0000 (reserved) Unable to handle kernel paging request at virtual address 5a5a5a92 c8845cc0 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c8845cc0>] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010282 eax: 5a5a5a5a ebx: c7f94000 ecx: c8848be0 edx: c7f94000 esi: c8842000 edi: 00000001 ebp: bffffe10 esp: c2bd1f68 ds: 0018 es: 0018 ss: 0018 Process rmmod (pid: 705, stackpage=c2bd1000) Stack: c7f94000 c8842000 00000246 c8845226 c1354460 c8842000 c8845fcd c7f94000 c8842000 c8845297 c884555e c011a00b c8842000 c02166c0 00000001 c01195fe c8842000 00000001 c2bd0000 4000a610 bffffe84 bffffe10 c010af10 00000000 Call Trace: [<c8842000>] [<c8845226>] [<c8842000>] [<c8845fcd>] [<c8842000>] [<c8845297>] [<c884555e>] [<c011a00b>] [<c8842000>] [<c01195fe>] [<c8842000>] [<c010af10>] Code: 8b 70 38 85 f6 74 21 8b 42 20 50 68 1c 83 84 c8 8d 5c 24 10
