So I'm guessing that you wrote your own initrd?

The main issue is that /sys/block/ is now full of symlinks, not real
directories, if CONFIG_SYSFS_DEPRECATED is not enabled.  That means that
any program that was doing stat() should be doing lstat() for the block
directory to work on all instances (remember, whenever looking for a
directory or a file in sysfs, it could be either a real file/directory
or a symlink, you should not care either way.)

People have also reported that for some reason, removing the '--movedev'
argument to switchroot is also needed, but that might just be a Fedora 7
specific thing, I'm not quite sure.

See the post from Alan Stern on lkml with the subject:
	Re: [RFC PATCH] /sys/block -> /sys/class/block  (Fedora 3 & 4 testers wanted)

for more details on that.

Hope this helps,
