I have seen this behavior before, on another system. FYI, I went to the console to reboot. CTL-ALT-DEL had no [immediate] effect. Then I hit the power button. Then these messages started appearing every 20 seconds on the console: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 928, size 4096 Screen shot here: http://www.flickr.com/photos/20922021@N04/4934586561/ I will probably power cycle the system to get it back. Given that the system goes unresponsive if I do an camcontrol, what debugging can I provide? -- Dan Langille - http://langille.org/
