The problem is still there, although I was able to boot into LFS just by removing one of the partitions in front of my LFS-partition, so that the LFS-partition had the same number as before the splitting. But the question still remains: why does the kernel panic when the partitionnumber of its rootdevice changes? -- -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
