VFS: Cannot open root device ...
I'm trying to port a 2.6 kernel to a V2Pro-based board that I've got. I get the following output when trying to boot:
RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem).
VFS: Cannot open root device "<NULL>" or unknown-block(0,0) Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I'm trying to use an initrd RAMDISK, and I've made sure that RAMDISK and initrd support are both enabled in the kernel configuration. Any ideas would be appreciated.
Cheers,
Chris Dumoulin

What boot loader are you using? In the boot loader where does it think the root fs is located? My guess is /dev/ram0 or something like that?
So I'd check your ramdisk to see that it has a /dev/ram0. Make sure you have rights to it.
