Hello,


i have finished my installation of LFS without any errors. Only the kernel
make me crazy.  I have 4 kernels compiled but ever come kernel panic.

The Message is:

VFS cannot open root device "sda2" or unknown block. 
Please append a correct root=


My settings:



linux-c4dc:/mnt/lfs/boot # ls -l
