ksymoops 2.4.8 on i686 2.5.63. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.63/ (default) -m /boot/System.map-2.5.63 (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_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod Machine check exception polling timer started. e100: selftest OK. e100: eth0: Intel(R) PRO/100 VE Network Connection e100: eth0 NIC Link is Up 100 Mbps Full duplex cs: IO port probe 0x0c00-0x0cff: clean. cs: IO port probe 0x0800-0x08ff: clean. cs: IO port probe 0x0100-0x04ff: excluding 0x3c0-0x3df 0x4d0-0x4d7 cs: IO port probe 0x0a00-0x0aff: clean. kernel BUG at include/linux/dcache.h:266! invalid operand: 0000 CPU: 0 EIP: 0060:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 00000000 ebx: c46be080 ecx: c12f3278 edx: c46be09c esi: c541b780 edi: 00000002 ebp: c46be080 esp: c4bcfeb8 ds: 007b es: 007b ss: 0068 Stack: c46be080 d09385d6 c46be080 c541b780 00000002 00000004 c541b780 c10afac8 d0937875 c46be080 c541b780 00000002 00000001 00000000 00000002 00000004 000f4240 0009f699 c56ddea4 00000000 c4645000 cee54180 dda6e025 0009f699 Call Trace: [] [] [] [] [] [] [] [] [] Code: 0f 0b 0a 01 96 68 2a c0 ff 42 e4 83 4b 04 08 b8 01 00 00 00 >>EIP; c015ca22 <===== >>ebx; c46be080 <__crc_idetape+35901e/39ec93> >>ecx; c12f3278 <__crc_skb_copy_bits+7e49c/1b217e> >>edx; c46be09c <__crc_idetape+35903a/39ec93> >>esi; c541b780 <__crc_interface_register+260d17/2e585b> >>ebp; c46be080 <__crc_idetape+35901e/39ec93> >>esp; c4bcfeb8 <__crc_set_transfer+4cc1c3/5513a8> Trace; d09385d6 <__crc_aio_put_req+3c7837/5223ba> Trace; d0937875 <__crc_aio_put_req+3c6ad6/5223ba> Trace; c0157cdc Trace; c0157fed Trace; c015819a Trace; c0157fed Trace; c01572ab Trace; c015742d Trace; c010921b Code; c015ca22 00000000 <_EIP>: Code; c015ca22 <===== 0: 0f 0b ud2a <===== Code; c015ca24 2: 0a 01 or (%ecx),%al Code; c015ca26 4: 96 xchg %eax,%esi Code; c015ca27 5: 68 2a c0 ff 42 push $0x42ffc02a Code; c015ca2c a: e4 83 in $0x83,%al Code; c015ca2e c: 4b dec %ebx Code; c015ca2f d: 04 08 add $0x8,%al Code; c015ca31 f: b8 01 00 00 00 mov $0x1,%eax 1 warning and 1 error issued.
