The patch was backported on 18 Apr., while Ubuntu natty was released on the end of Apr. So it is cruel to blame Ubuntu :-) The patch has already been backported to ubuntu kernel tree: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-natty.git;a=blob;f=kernel/futex.c;h=d5065e8283dac90ec20daf4eee4d530096d048ad;hb=HEAD#l1889 So, time will solve this problem, I think. If you want to solve this now, it would be good to consider installing a new kernel by kernel ppa or manual install. -- Yusuke Endoh
