Hi *! I got this Oops at unmounting a already renamed NFS source. The umount got a SEGFAULT. I compiled my 2.4.5 with 2.95.4 20010319 (Debian prerelease). Regards, -Gregor
ksymoops 2.4.1 on i686 2.4.5. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.5/ (default) -m /boot/System.map-2.4.5 (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.
