The patch you're referring to was committed I think along with another patch which caused some trouble in the -stable trees(I'm not surea bout that though :/). And in 2.6.32.37-rc1 it was reverted: [59/74] [PATCH] Revert "x86: Cleanup highmap after brk is concluded" Maybe it fixes your problem. -- Stratos Psomadakis
