Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.22-pre6aa1/ (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. Error (regular_file): read_system_map stat /usr/src/linux/System.map failed ksymoops: No such file or directory kernel BUG at shmem.c:490! invalid operand: 0000 2.4.22-pre6aa1 #1 SMP Thu Jul 17 20:24:29 MSD 2003 CPU: 0 EIP: 0010:[<801424cb>] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010202 eax: 00000508 ebx: 8d846a00 ecx: c7919800 edx: c79198fc esi: c79198fc edi: 8d846b40 ebp: 97b999a0 esp: af853e34 ds: 0018 es: 0018 ss: 0018 Process oracle (pid: 23274, stackpage=af853000) Stack: 8d846a00 8d846a00 80142460 c7919800 80161abf 8d846a00 00000000 00000000 97b999a0 8d846a00 8d846a00 8015e98e 8d846a00 97b999a0 97b999a0 97b999b8 8015ea5a 97b999a0 803349e0 8d141860 c78f6fa0 80148acb 97b999a0 9eb9f774 Call Trace: [<80142460>] [<80161abf>] [<8015e98e>] [<8015ea5a>] [<80148acb>] [<80132695>] [<8011c35a>] [<80121c66>] [<80128069>] [<80127f13>] [<80128115>] [<801073a8>] [<801236c4>] [<80123562>] [<80127546>] [<80115b50>] [<80117b80>] [<80107614>] Code: 0f 0b ea 01 24 c1 27 80 eb cd 0f 0b e9 01 24 c1 27 80 eb bc >>EIP; 801424cb <===== Trace; 80142460 Trace; 80161abf Trace; 8015e98e Trace; 8015ea5a Trace; 80148acb Trace; 80132695 Trace; 8011c35a Trace; 80121c66 Trace; 80128069 Trace; 80127f13 Trace; 80128115 Trace; 801073a8 <__read_lock_failed+11a8/17c0> Trace; 801236c4 Trace; 80123562 <__tasklet_hi_schedule+162/1a0> Trace; 80127546 Trace; 80115b50 Trace; 80117b80 <__verify_write+230/ab0> Trace; 80107614 <__read_lock_failed+1414/17c0> Code; 801424cb 00000000 <_EIP>: Code; 801424cb <===== 0: 0f 0b ud2a <===== Code; 801424cd 2: ea 01 24 c1 27 80 eb ljmp $0xeb80,$0x27c12401 Code; 801424d4 9: cd 0f int $0xf Code; 801424d6 b: 0b e9 or %ecx,%ebp Code; 801424d8 d: 01 24 c1 add %esp,(%ecx,%eax,8) Code; 801424db 10: 27 daa Code; 801424dc 11: 80 eb bc sub $0xbc,%bl 1 warning and 1 error issued.
