Thanks Bryan. It's still a mystery to me. I tried a 2.6.20.3 kernel last night and it still failed for me. Experimenting showed that the printf needs to be before the mmap function to make a difference, so I am hypothesizing that the issue is in mmap. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
