This is being felt by quite a number of users. See ubuntuforum threads 420296 and 413792.

I have tried all the workarounds suggested in the forums and none work.

For me, the failure of HIBERNATE on a laptop is a major issue. It cuts down boot and application start time, thus saving battery - vital on a business trip.

Suspend to RAM works with no apparent problem

Suspend to Disk apparently works, with disk acivity, then a period of quiscence, then some graphic mess in the top few lines of the screen, then a blank screen and a password box.

In /var/log/debug I have the lines
Apr 29 21:55:54 localhost kernel: [ 961.696000] agpgart-intel 0000:00:00.0: LATE suspend
Apr 29 21:55:54 localhost kernel: [ 961.696000] Back to C!
Apr 29 21:55:54 localhost kernel: [ 977.696000] agpgart-intel 0000:00:00.0: EARLY resume

Another Hibernate attempt produces the following:
Apr 29 22:53:36 localhost kernel: [ 4440.212000] agpgart-intel 0000:00:00.0: LATE freeze
Apr 29 22:53:36 localhost kernel: [ 4440.212000] swsusp: Normal pages needed: 123927 + 1024 + 24, available pages: 135355
Apr 29 22:53:36 localhost kernel: [ 4441.212000] agpgart-intel 0000:00:00.0: EARLY resume

The "page" problem gets worse with each subsequent HIBERNATE attempt (next lines generated with <grep swsusp ./debug>

I upgraded to Feisty in early April, and did not notice the Hibernate problem until late April, viz after a flurry of updates (but I cant remember which).

Hope this helps.
