[Bug 487339] [NEW] Resuming to black screen and frozen computer after suspend

[Christophe Charlot]

Public bug reported:

Binary package hint: hibernate

I have a Dell XPS studio 16 with ATI Mobility Radeon HD 4670 video card.

When I suspend the computer (to ram), everything seems to be fine, the
computer stops, and the power button blinks slowly.

When I press again the button, the computer seems to restart, but it
hangs with a black screen and I need to stop it with a looong press on
the power button.

I tried this wiki :

https://wiki.ubuntu.com/DebuggingKernelSuspend

You can find the Dmesg attached, but I've found no revelant information
in it.

If you need more infos, let me know, I'd be glad to help with this one.
