I have a bug in xpmem which shows up on our 8x oversubscription tests, but that is clearly my bug to figure out. Unfortunately it only shows up on a 128 processor machine so I have 1024 stack traces to sort through each time it fails. Does take a bit of time and a lot of concentration. > an hurry like we are, we can't progress without this. Infact we can SGI is under an equally strict timeline. We really needed the sleeping version into 2.6.26. We may still be able to get this accepted by vendor distros if we make 2.6.27.
