close it until the problem is fixed in the mainline.

This looks like a memory management bug.

The memory bitmap code used by the hibernation subsystem hasn't changed for a long time, so I guess the problem is architecture-related.

I'm afraid it will be difficult to pinpoint without bisecting.

Hmm.  Can you try the patch from bug #15286?
Comment 3 Rafael J. Wysocki 2010-04-21 05:46:57 UTC 
Sorry, typo.  Please try the patch from bug #15786.
