Hmm, well the sched-less-idle patch is in mm5, which brought 2.6.5-rc3-mm4 to 2320 on ext2.
The only other significant scheduler changes since that kernel are in -mm5. +sched_less_idle +sched_balance_context
So either sched_balance_context is causing a regression that counters sched_less_idle, or maybe it isn't a scheduler problem? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
