I'm clearly overlooking something, but I'm not sure what. the partitions found by ubuntu on SDAx will be found from your actual lfs-kernel according to the log on HDAx. you probably have still some old PATA drivers active. this driver seems to feel responsible for your disk on /dev/hda, and thus no driver is responsible for the same disk on /dev/sda. * second try: you copied the kernel to /dev/sda4/boot (on the LFS-partition) or /dev/sda2/boot (ubuntu)? copy it to both and play arround with root (hd0,X) kernel (hd0,Y)/boot/... where X/Y means all possible permutations with 1 and 3. (eventually try again with root=/dev/sda4 instead of hda4) tobias -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
