Initial test-drive looks good here, but I do see a regression. First the good news. fairtest2 is perfect, more perfect than ever seen before in fact. Mixed interval sleepers/hog looks fine as well (can't say perfect due to startup differences with the various proggies, but cpu% looks perfect). Amarok song switch time under hefty kbuild load is fine as well. I haven't done heavy multimedia testing yet, but will give it a more thorough workout later (errands). The regression: I see some GUI lurch, easily reproducible by running a make -j5 and moving the mouse in a circle... perceptible (100ms or so) lurches not present in rc5. -Mike - 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/
