(20060927) The blank screen happens with i386 as well. During the check, there is text showing each file being checked. Immediately after it finishes the check the screen clears. It can be typed into (and echos back). No other VTs can be switched to, and SysRq will display help, but will not display tasks or memory. SysRq-B does reboot, though.
One note about the progress bar: it seems to only cycle through the first 5% or so. ** Changed in: cdrom-checker (Ubuntu) Status: Unconfirmed => Confirmed ** Summary changed: - ppc desktop CD-ROM checker hangs forever + desktop CD-ROM checker hangs forever -- desktop CD-ROM checker hangs forever https://launchpad.net/bugs/60395 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
