ok, i've got something better to test: i separated the delta out into a more finegrained stack of 3 patches. You can pick them up from: http://redhat.com/~mingo/cfs-scheduler/older/sched-cfs-v2-rc0.patch http://redhat.com/~mingo/cfs-scheduler/older/sched-cfs-v2-rc0-preempt-fix.patch http://redhat.com/~mingo/cfs-scheduler/older/sched-cfs-v2-rc0-child-runs-first.patch http://redhat.com/~mingo/cfs-scheduler/older/sched-cfs-v2-rc0-misc.patch i test-built and test-booted all 4 steps of this. The baseline -v2-rc0 patch should be the one that works - you might want to double-check it, just to be sure. One of the other 3 patches ontop of this baseline causes the regression on your desktop. My current bet is on preempt-fix, so i have put that one first. The other one would be the second patch, child-runs-first. The misc patch should have no effect on behavior - but i've included it for completeness. (and i was wrong about the 'nice fix', it is not in this delta) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
