Hi, I got 2 BUG() messages for the same place when trying to restart a vserver. System: Dell 1425SC, Dual Xenon with AMD64 Kernel Kernel: 2.6.13.4 Vserver: 2.6.13.1-vs2.1.0-rc2 Regards Andreas *************** First Opps: ksymoops 2.4.9 on x86_64 2.6.13+vserver. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.13+vserver/ (default) -m /boot/System.map-2.6.13+vserver (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.
