Binary package hint: casper
Testing alpha2 candidate (20100112.1) lucid-desktop-i386 image (burned to cd). Upon clicking shutdown in the live environment, the cd is ejected & then the laptop hangs with the Ubuntu logo displayed. "Please remove the disc and close the tray (if any) then press ENTER" is not displayed. Pressing Enter did nothing. Cycling through the various ctrl-alt-"F" combinations displays "The system is going down for halt NOW!" but the laptop just hangs. Ultimately I need to perform a hard power off. This happens on every shutdown from the live environment.
Further testing revealed that an installed system from the same disc reboots & shuts down normally.
