Apr 30 12:51:00 pollux kernel: invalid operand: 0000
This begins a cascade of similar messages, after which almost anything I
try to do results in a segfault.
The system is an Athlon on an Epox 8KTA3, with BIOS flashed up to
17-Apr-2001.
The kernel is 2.4.4, compiled as a PIII (since I still can't get an
Athlon kernel to boot.)
I'm subscribed now, so I'll see any requests for more information.
=====
% ksymoops oops.txt # File contains only the first in the cascade.
ksymoops 2.4.0 on i686 2.4.4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.4/ (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_maps): ksyms_base symbol
__VERSIONED_SYMBOL(shmem_file_setup) not found in System.map. Ignoring
ksyms_base entry
