Hi,
ok, when I boot up my system, then, with a chance of about 1/20 the kernel will not boot, but have an Oops instead. I copied it down, and ran it through the ksymoops... I hope its usable. If you have questions, just ask back (as I dont realy know what information you need)
here is the output of ksymoops: --------------------------- ksymoops 2.4.5 on i686 2.4.19-pre7-lowlatency. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.19-pre7-lowlatency/ (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.
