| |
I got this OOPS while unloading the ns558 module.. I don't think it did this in 2.4.0-test8, but I don't recall ever unloading it in test8..
I've attached the ksymoops output..
-- Zinx Verituse (See headers for gpg/pgp key info)ksymoops 2.3.4 on i686 2.4.0-test9. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.0-test9/ (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.
Warning (compare_ksyms_lsmod): module ns558 is in lsmod but not in ksyms, probably no symbols exported Unable to handle kernel NULL pointer dereference at virtual address 00000004 c01dbaa7 *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c01dbaa7>] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 00000000 ebx: 00000000 ecx: cf799000 edx: 00000000 esi: d0820a20 edi: d0820000 ebp: bfffe7cc esp: ccce7f80 ds: 0018 es: 0018 ss: 0018 Process modprobe (pid: 13294, stackpage=ccce7000) Stack: 00000000 fffffff0 d0820696 d0820a20 d0820000 c011afd3 d0820000 fffffff0 c5070000 bfffe7cc c011a477 d0820000 00000000 ccce6000 00000000 bffffb15 c010a32f bffffb15 bffffb15 00000000 00000000 bffffb15 bfffe7cc 00000081 Call Trace: [<d0820696>] [<d0820a20>] [<d0820000>] [<c011afd3>] [<d0820000>] [<c011a477>] [<d0820000>] [<c010a32f>] Code: 89 50 04 89 02 8b 1d c8 c2 2a c0 81 fb c8 c2 2a c0 74 29 8d
