Really strange.  This message is printed when wait_load_disk fails.

The kernel has probed all disks before, then apparently something
is installed using dpkg and then it waits for this rootfs (which
obviously isn't the root at that point).

Also at least on my debian testing and oldstable systems a plain
blkid call never even calls SG_IO or related ioctls (which makes sense
given that it looks at the file system labels).

Does tis issue just show up on one particular system or on multiple
different ones?
