Hi All, I am trying to decode and find out the cause of the error through oops. But, I am facing a problem <<<< some oops msgs EIP is at __d_lookup+0xc5/0xe7 [ 280.626128] Code: 08 00 85 c0 75 17 31 f6 f6 43 04 10 75 05 f0 ff 03 89 de 8b 45 e4 e8 42 12 1e 00 eb 26 8b 45 e4 e8 38 12 1e 00 8b 3f 85 ff 74 16 <8b> 07 0f 18 00 90 8d 5f d8 8b 4d ec 39 4b 34 75 e9 e9 75 ff ff [ 280.626174] EIP: [<c0163196>] __d_lookup+0xc5/0xe7 SS:ESP 0068:f151be84
some oops msgs
As EIP indicates __d_lookup(), I did following steps # objdump -d fs/dcache.o > fs/dcache.disasm # make fs/cache.s Opened fs/dcache.disasm found __d_lookup() int it, it starts at address 0x865 00000865 <__d_lookup>: 865: 55 push %ebp # printf "%x\n" $((0x865+0xc5)) 92a The code present at 92a does not match with the code displayed in the oops msg 926: 85 ff test %edi,%edi 928: 74 16 je 940 <__d_lookup+0xdb> ********* 92a: 8b 07 mov (%edi),%eax 92c: 8d 74 26 00 lea 0x0(%esi),%esi 930: 8d 5f d8 lea 0xffffffd8(%edi),%ebx 933: 8b 4d ec mov 0xffffffec(%ebp),%ecx 936: 39 4b 34 cmp %ecx,0x34(%ebx) 939: 75 e9 jne 924 <__d_lookup+0xbf> 93b: e9 75 ff ff ff jmp 8b5 <__d_lookup+0x50> Why is it so? I think the code should be matching. Thanks and Regards, Prasad. ADDING CALL TRACE IF REQUIRED FOR REFERENCE.
