One thing you might try is this. Change the bootscripts to not run udevd (or the retry). The system should come up fine, but some symlinks or permissions may be missing/wrong. The run from the command line as root: /lib/udev/udevd --debug |tee /run/udev-debug.log You should be able to get some info about how udev perceives the cdrom. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
