ksymoops 2.4.6 on i686 2.5.41. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.41/ (default) -m /boot/System.map-2.5.41 (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. 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 0x4d0-0x4d7 cs: IO port probe 0x0a00-0x0aff: clean. kernel BUG at mm/page_alloc.c:95! invalid operand: 0000 CPU: 0 EIP: 0060:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00013202 eax: 01000001 ebx: c11d2360 ecx: 00000000 edx: 00000001 esi: cba7c000 edi: 00000000 ebp: 00000000 esp: cd047ea8 ds: 0068 es: 0068 ss: 0068 Stack: c11d2360 cba7c000 ce691800 00000000 ce691800 00000000 00003286 cba7d400 d07d5000 ce691800 00000000 c0110a7f cba7d400 c012f401 c012f434 d0240301 c11d2360 ce4de2a0 ce51a800 d0240347 ce691800 cba7c000 cd047f2c bffffc2c Call Trace: [] [] [] [] [] [] [] [] [] [] [] Code: 0f 0b 5f 00 ae 1d 28 c0 89 f6 8b 03 a8 40 74 0a 0f 0b 60 00 >>EIP; c012e946 <__free_pages_ok+66/2e8> <===== >>ebx; c11d2360 <_end+e56044/fdf5d44> >>esi; cba7c000 <_end+b6ffce4/fdf5d44> >>esp; cd047ea8 <_end+cccbb8c/fdf5d44> Trace; c0110a7f Trace; c012f401 <__free_pages+29/2c> Trace; c012f434 Trace; d0240301 <[i830]i830_free_page+55/5c> Trace; d0240347 <[i830]i830_dma_cleanup+3f/a4> Trace; d024092f <[i830]i830_dma_init+af/cc> Trace; d0240880 <[i830]i830_dma_init+0/cc> Trace; d023bfe6 <[i830]i830_ioctl+da/e8> Trace; c0147ee9 Trace; c010714d Trace; c0106fcb Code; c012e946 <__free_pages_ok+66/2e8> 00000000 <_EIP>: Code; c012e946 <__free_pages_ok+66/2e8> <===== 0: 0f 0b ud2a <===== Code; c012e948 <__free_pages_ok+68/2e8> 2: 5f pop %edi Code; c012e949 <__free_pages_ok+69/2e8> 3: 00 ae 1d 28 c0 89 add %ch,0x89c0281d(%esi) Code; c012e94f <__free_pages_ok+6f/2e8> 9: f6 8b 03 a8 40 74 (bad) 0x7440a803(%ebx) Code; c012e955 <__free_pages_ok+75/2e8> f: 0a 0f or (%edi),%cl Code; c012e957 <__free_pages_ok+77/2e8> 11: 0b 60 00 or 0x0(%eax),%esp 1 warning issued.
