Out of curiosity, how did you find v2.6.38-rc1~216 (mm: page allocator: adjust the per-cpu counter threshold when memory is low, 2011-01-13)? Is there a corresponding RH bugzilla entry with details? I thought that patch fixed a regression introduced by v2.6.32.23~22 (mm: page allocator: calculate a better estimate of NR_FREE_PAGES when memory is low and kswapd is awake, 2010-09-09), which would correspond to version 2.6.32-24 of the linux-2.6 package, but the original report was against 2.6.32-21. Moreover, 2.6.32-24 was not uploaded until after a couple of weeks after the original report. Hmm. Thomas, if you get a chance to try a kernel from sid or experimental, that would be interesting.
