Basically this means that a developer thought that a certain situation should never be happen and if it does, execution should stop. It is possible to ignore this and continue executing: config BUG bool "BUG() support" if EXPERT default y help Disabling this option eliminates support for BUG and WARN, reducing the size of your kernel image and potentially quietly ignoring numerous fatal conditions. You should only consider disabling this option for embedded systems with no facilities for reporting errors. Just say Y. A kernel oops is basically a crash. This can be caused by bad memory accesses and things like that. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
