    lol
    ...which is why I got my dream phone (D1) two years after launch and I'm cruising Craigslist for 1-year-old phones.
    Maybe I'll get a Droid X next or an Evo...
    Can't afford new stuff and don't want to be an 'early adopter'.
    There is value in following the big trends!

    Btw, I've been wondering this for awhile...maybe you can answer, prime. Why is it the Droid has kernels capable of 1.25 GHz+ when the rated processor speed was 600 but other phones can't be overclocked that much? (Basically how can we overclock the Droid more than double rated speed but other phones barely get more than a couple MHz faster?)

    It boils down to the OMAP3430 being highly over-engineered basically. Not many processors can achieve a 50% overclock.

    Now I'm having an odd issue with this kernel...nothing big but a few benchmark apps don't work properly, mainly antutu benchmark and rl benchmark...antutu freezes mid test and rl benchmark doesn't run its benchmarks at all...weird???

    Sounds like your vsels are too low.

    Hmm, the values must have been on the very edge of what they should be for my phone then because before doing my few little tweaks everything worked fine...I'll try bumping the higher speed slot ones by 1 or 2 and see if it helps

    Edit: didn't really change anything raising the vsels...I guess your kernel just doesn't like having extra tweaks lol...oh well, I was planning on switching roms soon anyway, I'll let ya know how it runs on miui rom when I get it set up :)

    Runs great on miui for myself anyway. Low vsel values can have detrimental effects causing force closures, overheating and other general strange behavior.

    Zeps scripts cause issues with or without my kernel, I tried v6 on my X and it caused random rebooting and an increased amount of force closures. While a good idea I find they cause more problems than they solve, much like swap.

    Yeah, I just changed my top slot from 1250 down to 1200 with the same vsel of 80 and it's much better now...I guess every phone/rom/kernel/extra scripts setup behaves differently...oh well, I can live with it...btw is it just me or does miui handle graphics differently than other roms? Its seems like the graphics are way better for some reason

    Btw, what do you think of different I/O schedulers? I know noop, deadline and cfq are the most popular especially for Android phones but what about any others? I'm just asking because according to Zeppelinrox kickasskernel I/O tweak it says sio is preferred over deadline which is preferred over noop which is preferred over cfq...I don't know a whole lot about the schedulers so I'm not sure if that's right or not...I haven't even seen the sio scheduler in any kernels though

    I think CFQ performance is best, deadline is most compatible, noop is simplistic and SIO I have no experience with.

    Hmm, I wouldn't mind comparing the different ones but what would be a script to change the I/o scheduler be though? (Specifically how to change to noop)

    Run this script in a su term:

    for i in /sys/block/*
    do
    echo noop > $i/queue/scheduler
    done

    Or download here and run: http://db.tt/YCffbAg
