Subject: 2.6.32.2 page allocation failures


My 2.6.32.2 from kernel.org is generating a large number of page 
allocation failures.

Please cc; I'm not subscribed.  Portions of .config below.

Are there workarounds? KSM is in the kernel but not activated 
(/sys/kernel/mm/ksm/run is 0).

The distro is an up-to-date Debian squeeze, amd64.

Cheers,
Dave
