Have you read this guide: http://alien.slackbook.org/dokuwiki/...kernelbuilding
"In case your kernel does not include the driver for your root filesystem, or a driver for your SATA bus, or other stuff that is only built as modules, your kernel will panic if it boots and can not access the necessary disks, partitions and/or files. Typically, this looks like"
VFS: Cannot open root device "802" or unknown-block (8,2)
Please append a correct "root=" boot option
Kernel Panic-not syncing: VFS: unable to mount root fs on unknown block(8,2)
You should create a initrd.gz (or whatever you name it) with mkinitrd.
