So, if you have both the good and the bad versions, diff them to identify what you changed and then reinstate things you've removed, and remove things you've added, until the kernel works. Alternatively, start from the working kernel config, and try again to enable wireless. Don't change a lot of options at a time. Once you have it workng satisfactorily, I suggest you update the kernel to either the latest 3.2 (3.2.12 at the moment - 3.1 is no longer maintained), or to the latest 3.3 (currently 3.3 itself). NB - just because a config works fine on one machine doesn't mean it will work fine on another, even if they are *nominally* identical machines - often, some of the hardware can differ (e.g. different revisions of a particular chip), or different bios settings can make things work differently. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
