This is the vmlinux.lds.S problem. The cleanup patch from Sam Ravnborg moved the __initramfs_start and __initramfs_end symbols into the .init.ramfs section. This is in itself not a problem, but it surfaced a bug: there is no *(.init.initramfs), that needs to be *(init.ramfs). I corrected this in the upstream patch but 2.6.23-mm1 has the older one that still causes the "Cannot open root device". For 2.6.23-mm1 use the patch below. -- blue skies, Martin.
