Comment 17 for bug 194314

I tried a pm-suspend from console, and had the same hang on resume. If it is of any interest, a small note: with the AC cord plugged in, when I first boot up (before loading an OS) or resume from suspend in Windows, an LCD backlight turns on under a little built-in hardware status panel with symbols for power, battery status, disk, caps lock type things. But when I resume from suspend in Ubuntu, the backlight doesn't turn on. Also, caps lock symbol doesn't display.

That's all I can think to try.
