I would use the smallest config that allows me to boot the system and reproduce the bug. A good starting point is /proc/config.gz from the running system. allmodconfig is just sticking the knife in and twisting unnecessarily. > I haven't done this in a while and I'm still going thru the xconfig, > stripping out modules for hardware I don't have, but if I just transfer the > old ones in, they should work but will be building about 1400 modules > extra. You may want to try the opposite approach. x86_64_defconfig, then add just what is necessary to boot and reproduce the bug. hth, Jason. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
