I'm afraid I have to agree with Laszlo, that this patch unfortunately does not cure the aarch64 race. The test case I'm using is: http://git.annexia.org/?p=rhbz1184405.git;a=tree Note: This does not mean this patch is bad! Just that it doesn't cure the long-standing aarch64 race that we've been trying to fix forever, which is what we were hoping.
