Hi,
I think this is 2.6.21 material.
--- From: Rafael J. Wysocki <rjw@sisk.pl>
Fix a bug in the swsusp's memory shrinker that causes some systems using highmem to refuse to suspend to disk if image_size is set above 1/2 of available RAM.
Special thanks to Jiri Slaby for reporting the problem and assistance in debugging it.
