[okl4-developer] okl4 off the disk

[Ashish Bijlani]

I added the required PCI ID to drivers/ata/ata_piix.c and the kernel
is able to mount the root file system residing on /dev/sda5. However,
it fails when it goes further and tries mounting udev; says  - no
space left on device. Also, the keyboard doesn't work with the booted
kernel. If I skip all the services by passing "init=/bin/bash"
argument to the kernel command line, I see bash shell after VFS mounts
the root file system (/dev/sda5). However, keyboard doesn't work. Any
suggestions? Thanks.
