Hi Karol,

Hi,

I've tried merging 'akpm' (517d08699b25) into clean 2.6.30 tree and
got suspend-breakage which makes it untestable for me.  (I've tried
reverting drm, suspend, and other commits... all that failed.)

Is there mm-related git tree hidden somewhere?  ... or broken out
mm-related patches that were sent to Andrew ... or maybe it's possible
to get "git log -p" from Mel's private repo?  Anything?

Please try reverting 373c0a7e + 8aa7e847 [1] on top of 2.6.31. I've finally 
been able to solidly trace the main regression to that. I'm doing some 
final confirmation tests now and will mail detailed results afterwards.

It would be great if you could confirm if that fixes the issue for you too.

Sadly, reverting these patches didn't fix my problem.  I've just
tested it -- I still get allocation failures.

Thanks.
