i have just tried the same workload with cfs and with sd048 from -ck, and cannot reproduce this. To make sure it's not some other change in -ck, could you try the pure SD patches ontop of 2.6.21.1 too: http://www.kernel.org/pub/linux/kernel/people/ck/patches/2.6/2.6.21/2.6.21-ck2/patches/2.6.21-sd-0.48.patch http://www.kernel.org/pub/linux/kernel/people/ck/patches/2.6/2.6.21/2.6.21-ck2/patches/sched-sd-0.48-interactive_tunable.patch 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/
