Why does my Lion 10.7.3 boot fail at "still waiting for a root device" ?

I use Lion on two different machines and I haven't seen that message. A google search shows that a bunch of people have had that problem, though. Maybe one of those forums or web sites have solutions:

Thank you, this happens after I installed and updated iTune yesterday. Now the boot process stops while the OS is being loaded and I am so confused.

Are there multiple "hard drives" in this environment? If so, it's possible that the logical drive number was changed. When booting on a real system instead of via VMWare, the logical drive numbers are assigned in the BIOS, and can be changed by changing device and/or boot order of the hard drives.
