    SUpercharger could be the culprit... I ran it not knowing I currently had busybox v 1.19 CM. I thought I had used it prior to this on my current ROM install, without first changing busybox, but there is a chance I did not. I will pursue this further.


    Prime, I'd just like to say you RULE for taking time out to help people like this, especially when it's an issue that has pretty much nothing to do with your kernel. Thanks a lot for all your help.

    Please try this in a terminal and show me the output:

    I have a few quick questions for ya, prime...where is a good site to learn different scripts? I know some but not too many...are they just basic Linux knowledge? Oh and how hard is it to learn Linux and compiling kernels and even roms? If it's not super hard I wouldn't mind diving into android and kernel development myself

    Anyone can compile a kernel -- well it's a little bit of a pain to get things set up -- however its a whole different ball of wax to go about tweaking it. Same goes for ROMs. if you want to get into the game, install a linux distro and get used to it, then start writing simple programs for Android. I think Cyanogen had an article about how to get into the whole android thing which made for pretty good advice with a logical progression -- and it didn't start out by kernel tweaking.

    Do you mean scripting or linux commands?

    This is the best guide to bash scripting (downloadable in various forms as well): http://tldp.org/LDP/abs/html/

    I forget how many kernel options there are but its extremely easy to break things by enabling/disabling a single wrong switch. Best to start with compiling kernels for a PC, then move on to embedded.

    The cyanogen mod wiki and cvpcs's blog are good places to start reading up on various forms of android development. Grab the android SDK/eclipse and go through the available tutorials to get a handle on android app development.

    I think I may have figured out what the problem is, actually Prime was the one who helped me out when it reared it's ugly head.
    It sounds like when you were messing with settings and partition tweaks, you may have accidentally formatted the 2nd partition perhaps to linuxswap.
    This is why you are getting all the output to commands and queries as busy or doesn't exist.
    I have had 2 encounters with this, once was caused by something unknown and the other time I accidentally reformatted it using swapper2.
    I think that the only solution is to reformat the partitions. Sucky, yes. But I believe that it is the only way to fix this.

    Please chime in, if anyone agrees or disagrees. Or, just wants to give a yea yo!

    Hopefully this will work and all will be right in this world, meaning all will be continuing to fall to pieces around us.
