ksymoops 2.3.4 on i686 2.4.0-test6. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.0-test6/ (default) -m /boot/System.map-2.4.0-test6 (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. invalid operand: 0000 CPU: 0 EIP: 0010:[] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010286 eax: 0000001c ebx: c105aa40 ecx: c01df62c edx: 00000001 esi: c55fc2bc edi: 0000f22f ebp: c123163c esp: c55f5f1c ds: 0018 es: 0018 ss: 0018 Process bonnie (pid: 473, stackpage=c55f5000) Stack: c01b9645 c01b97c7 00000043 c105aa40 c0120ca0 c105aa40 c123163c c105aa40 c55f5f98 0f22f000 00000000 c0123283 c105aa40 c55fc2bc 0000f22f c123163c c5b71740 ffffffea 00000000 00001000 00001000 00000000 c123163c 00000000 Call Trace: [] [] [] [] [] [] [] Code: 0f 0b 83 c4 0c 5b c3 90 53 8b 5c 24 08 8b 43 18 a8 01 75 16 >>EIP; c01203dc <__add_page_to_hash_queue+3c/44> <===== Trace; c01b9645 Trace; c01b97c7 Trace; c0120ca0 Trace; c0123283 Trace; c0129f2b Trace; c010a2df Trace; c010002b Code; c01203dc <__add_page_to_hash_queue+3c/44> 00000000 <_EIP>: Code; c01203dc <__add_page_to_hash_queue+3c/44> <===== 0: 0f 0b ud2a <===== Code; c01203de <__add_page_to_hash_queue+3e/44> 2: 83 c4 0c add $0xc,%esp Code; c01203e1 <__add_page_to_hash_queue+41/44> 5: 5b pop %ebx Code; c01203e2 <__add_page_to_hash_queue+42/44> 6: c3 ret Code; c01203e3 <__add_page_to_hash_queue+43/44> 7: 90 nop Code; c01203e4 8: 53 push %ebx Code; c01203e5 9: 8b 5c 24 08 mov 0x8(%esp,1),%ebx Code; c01203e9 d: 8b 43 18 mov 0x18(%ebx),%eax Code; c01203ec 10: a8 01 test $0x1,%al Code; c01203ee 12: 75 16 jne 2a <_EIP+0x2a> c0120406 1 warning issued.
