Hello; I was receiving this last week,
wasn't receving this:
Pid:1,comm:swapper Not tainted

but was having this:
VFS: Cannot open root device
what was causing this is grub from dapper,feisty,etc..
if you compile you're kernel with initrd.img then will work,
but if you: make you're kernel statically(make, make install)
it will produce unable to mount vfs.
downgrade grub or use grub2.
if you've already did that, then I don't know.
regards;
