I go the following Oops whilts un-taring the XFree86 sources.
Machine:
AMD k6-2+ 500Mhz 128MB ram.
.config, and results from /proc/pci and dmesg are attached.
ksymoops 2.4.8 on i586 2.4.21-pre3-ac3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre3-ac3/ (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.
