    I now also have built MV kernels for those folks who even struggle with LV - am interested to hear if it helps you or not.

    These kernels all have TUN built-in. You will also see links for cifs.ko and ext2.ko if you wish to use those.

    I am too tired to get into many more details - but here they are:

    Enjoy!

    Chevy, thanks so much for putting together the MV kernels! Trying now.

    On a different note, when you get a chance, would you please help me understand in what circumstances I might need the cifs.ko and/or ext2.ko that you've provided? Thanks!

    the ext2.ko is a kernel module for mounting ext2 filesystems, which are a type of linux filesystem. i use an ext2 image on my droid so i can run debian on top of android and run debian applications (most notably, the IM client finch). other people use ext2 partitions on their sdcard for swap space and other things. ext2 has been superseded by ext3 and ext4, but they're not working with the froyo kernel at the moment.

    ext2 - Wikipedia, the free encyclopedia

    the cifs.ko i assume is used to be able to mount windows network filesystems on the droid. that's what the cifs module does on regular linux systems. i haven't tried that because i'm thankfully linux-only at home, so i don't have any cifs shares.

    Server Message Block - Wikipedia, the free encyclopedia

    chevy, if cifs.ko is used to mount windows filesystems, have you ever considered trying to compile nfs support for the android kernel for linux/unix shares?

    I noticed something interesting today. I decided to try upgrading to the 1.25 GHz ulow voltage kernal for the first time. I hadn't tried before(on 4.0) because the 1.0 ulow was working perfectly and I had no reason. I decided to see if I could get a quadrant core over 1500, just for s's and g's so I applied the 1.25 ulow update.zip. Booted up fine, didn't seem to have any issues, got a 1498 :icon_evil: in quandrant, but then I noticed that the wifi wouldn't turn on. I had the Power Control widget on the screen and when i hit the wifi button, it lights up, but not all the way. It turns just a dim blue, while things like GPS and sync are a deep blue.

    I went into settings and tried to turn wifi on there as well, and it would try for a second, then it just said error and stopped.

    I tried flashing up to 4.1 at thie point(seeing as I was already waist deep in it) but the activation wizard(after wiping) kept force closing. I just reflashed my 4.0 image and am running fine again (on wifi now actually) on the 1.0 GHz ulow, but I was wondering if this had happened to anyone else?

    I didn't see this posted at all, so I don't know if I'm the only one who's experienced this. Not a problem at all since 1.0 GHz ulow runs fast and cold on my Droid. Just a curious observation. Any thoughts?

    yes, and functionally you are not missing anything other than a correct label on the kernel (some were incorrect), and cifs/ext2 - if you don't need those, no need to upgrade

    ok, just so I have it straight - you downloaded/installed the 1.25 ULV from this thread, and then basically wifi was broken - right? Will test!

    Yep - I am really impressed as well. I was using one on Pete's .02, but the ROM started giving me problems, so I went back to 1.1. I am really hoping there is a ULV for 1.1, (Which is Android 2.1), but I havn't found one yet.

    Does anyone know if there is a ULV that will work on Pete's BB 1.1?

    Take care,
    Rob

    They work flawless for me, so I don't know what to say other than moving up the voltage, or having a lower clock speed.

    Anybody know why with the new kernels the "conservative" setting is now eliminated from the setCPU options? I loved it because it helped me save battery and kept my phone cool...

    Any ideas on how I can get it back?
