I just got this and I'm a few kernels out .. but I thought I'd throw this way in case it hasn't popped up or been fixed..
I was compiling mopd on a AMD K6-400, 64MB RAM and it oops on the first gcc.. machine was doing nothing much, no X, 3 sshs to a remote machine...
Mandrake 8.0.
Dave.
ksymoops 2.3.7 on i586 2.4.13-pre5. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.13-pre5/ (default) -m /boot/System.map-2.4.13-pre5 (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.
