Just now, I did a fresh install from the 09-April-2006 daily build, plus all current updates for Ubuntu and Kubuntu-Desktop.

Suspend-to-RAM works, but Resume-from-RAM experiences a short delay (a driver timeout in libata is suspected), and then the USB mouse lights up (working), and the hard disk light locks on solid. The display backlight never comes on, so no messages are visible, and the system is not functioning.

Alt-SysRq-B works (reboot), so it's not a total hard lockup.

It really looks like the libata hard disk device is not surviving the resume operation. I may eventually apply Randy Dunlop's libata-acpi patchset and see if that cures it.

Cheers
