ksymoops 2.4.3 on i686 2.4.17. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.17/ (default) -m /boot/System.map-2.4.17 (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. No modules in ksyms, skipping objects Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file? cpu: 0, clocks: 1339366, slice: 446455 cpu: 1, clocks: 1339366, slice: 446455 kernel BUG at dcache.c:654! invalid operand: 0000 CPU: 1 EIP: 0010:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010286 eax: 0000001c ebx: f7a82210 ecx: c028dce0 edx: 00003733 esi: f7a7bd60 edi: f7a821e0 ebp: f7a821e0 esp: f7a6bf08 ds: 0018 es: 0018 ss: 0018 Process devfsd (pid: 25, stackpage=f7a6b000) Stack: c0240a13 0000028e f6829ba0 f7a7bd60 f7a7f480 c016a33f f7a821e0 f7a7bd60 f7a821e0 00000000 f7a6bfa4 f7a9c6a0 c013be5e f7a821e0 00000000 f7a6bf74 c013c6c1 f7a9c6a0 f7a6bf74 00000000 f7a28000 00000000 f7a6bfa4 00000009 Call Trace: [] [] [] [] [] [] [] [] Code: 0f 0b 83 c4 08 f0 fe 0d a0 36 2e c0 0f 88 d3 64 0e 00 85 f6 >>EIP; c0144b52 <===== Trace; c016a33e Trace; c013be5e Trace; c013c6c0 Trace; c013c94a Trace; c013ce30 <__user_walk+34/50> Trace; c013984c Trace; c0132824 Trace; c0106dba Code; c0144b52 00000000 <_EIP>: Code; c0144b52 <===== 0: 0f 0b ud2a <===== Code; c0144b54 2: 83 c4 08 add $0x8,%esp Code; c0144b56 5: f0 fe 0d a0 36 2e c0 lock decb 0xc02e36a0 Code; c0144b5e c: 0f 88 d3 64 0e 00 js e64e5 <_EIP+0xe64e5> c022b036 Code; c0144b64 12: 85 f6 test %esi,%esi 2 warnings issued.
