All right, this is one of my two or three "BSOD" since I use Linux :-) Not sure if I did ksymoops right. I hope this is useful
$ /sbin/ksymoops ksymoops 2.4.9 on i686 2.6.1-rc2-mm1. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.1-rc2-mm1/ (default) -m /usr/src/linux/System.map (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 /sbin/ksymoops: No such file or directory No modules in ksyms, skipping objects No ksyms, skipping lsmod Reading Oops report from the terminal Unable to handle kernel paging request at virtual address 193d2029 printing eip: c0152546 *pde = 00000000 Oops: 0000 [#1] PREEMPT CPU: 0 EIP: 0060:[<c0152546>] Tainted: PF VLI EFLAGS: 00010202 eax: 00000000 ebx: d9fb0008 ecx: c0260a74 edx: c140f388 esi: 193d2025 edi: 00000000 ebp: 00000100 esp: da29def4 ds: 007b es: 007b ss: 0068 Process kdeinit (pid: 4298, threadinfo=da29c000 task=d9e18ce0) Stack: d9893720 00000001 c0152951 da29df48 00000000 00000000 00000010 00000008 000000b8 00000000 00000000 000000b8 da2de7ac da2de7a8 da2de7a4 da2de7b8 da2de7b4 da2de7b0 7fffffff 00000008 00000000 c0152577 d9fb0000 00000000 Call Trace: [<c0152951>] [<c0152577>] [<c0152c93>] [<c0227f0e>] Code: d9 fb ff ff 90 8b 44 24 04 c7 00 77 25 15 c0 c7 40 08 00 00 00 00 c7 40 04 00 00 00 00 c3 56 53 8b 44 24 0c 8b 70 04 85 f6 74 2e <8b> 5e 04 83 eb 1c 8b 43 18 8d 53 04 e8 39 58 fc ff 8b 03 e8 d3 Badness in unblank_screen at drivers/char/vt.c:2793 Call Trace: [<c01ccfb6>] [<c0114c9b>] [<c010a87f>] [<c0115233>] [<c0115e0d>] [<c0116afe>] [<c0114f12>] [<c02289e7>] [<c0152546>] [<c0152951>] [<c0152577>] [<c0152c93>] [<c0227f0e>] Unable to handle kernel paging request at virtual address 193d2029 c0152546 *pde = 00000000 Oops: 0000 [#1] CPU: 0 EIP: 0060:[<c0152546>] Tainted: PF VLI Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010202 eax: 00000000 ebx: d9fb0008 ecx: c0260a74 edx: c140f388 esi: 193d2025 edi: 00000000 ebp: 00000100 esp: da29def4 ds: 007b es: 007b ss: 0068 Stack: d9893720 00000001 c0152951 da29df48 00000000 00000000 00000010 00000008 000000b8 00000000 00000000 000000b8 da2de7ac da2de7a8 da2de7a4 da2de7b8 da2de7b4 da2de7b0 7fffffff 00000008 00000000 c0152577 d9fb0000 00000000 Call Trace: [<c0152951>] [<c0152577>] [<c0152c93>] [<c0227f0e>] Code: d9 fb ff ff 90 8b 44 24 04 c7 00 77 25 15 c0 c7 40 08 00 00 00 00 c7 40 04 00 00 00 00 c3 56 53 8b 44 24 0c 8b 70 04 85 f6 74 2e <8b> 5e 04 83 eb 1c 8b 43 18 8d 53 04 e8 39 58 fc ff 8b 03 e8 d3

This architecture has variable length instructions, decoding before eip is unreliable, take these instructions with a pinch of salt.
