Re: root=/dev/ram0

Hi,


Can you give the following details,
Are you trying to load it as initrd? Not I assume, else confirm that
CONFIG_BLK_DEV_INITRD=y

Incase you are setting /dev/ram0 as the rootfs using rdev or equivalent,
how does the rootfs end up on the ramdisk when the kernel starts up?

ps - Did not mean to skip the list.
