Temporarily dead optical drive

[David Munson]

I had this happen this past weekend while playing with a couple of
livecds on a WinXP laptop. No idea why it happened, but I had to
reboot using the power button (i'd exited the distro, and was trying
to remove the cd so the laptop wouldn't boot from it again), then use
the boot options menu to get into Windows, then have windows eject it.

Two totally different distributions, not even based off the same main
distribution, but same version of the kernel. Really weird.
