Looks like you've got it after all! With the patch in the correct place there are no more skips and I now get: /proc/5182/task/5182/sched:se.bonus_max : 39.960966 /proc/5182/task/5263/sched:se.bonus_max : 39.960966 /proc/5182/task/5267/sched:se.bonus_max : 39.960966 /proc/5182/task/5268/sched:se.bonus_max : 39.960966 /proc/5182/task/5269/sched:se.bonus_max : 39.960966 /proc/5182/task/5270/sched:se.bonus_max : 19.990234 /proc/5182/task/5661/sched:se.bonus_max : 39.960966 Note (mostly for Parag) that I had GROUP_SCHED disabled for these tests, but for me that did make not any difference with my 2.6.25-rc tests for this issue, nor with my tests using sched-devel earlier in the .26 merge window.
