    Do you have a /data/sdext2 directory? Do you have a linux machine? The only thing I can think of is your second sd partition is not formatted properly.

    The reason I ask if you have a linux machine is to see if your ext4 partition will properly mount on a linux machine.

    Are the mount commands being ran as root?

    I do not have a linux machine unfortunately. This partition has been working for about 4 months, with an issue maybe once every 10 reboots where the partition did not mount properly, and a reboot would fix.

    All commands are being run as root.

    Holy crow - /data/sdext2 does exist, and in it is a dalvik-cache dir

    Could you verify that your /data/sdext folder exists?

    I can see it and cd into it. It's definitely there.

    Ok. My final suggestion is pull the busybox binary from a current CM nightly and replace the version your currently using, if this does not repair your issue perhaps you should talk with zepp as after running the supercharge script your problems began.

    Maybe changing busybox in the first place messed it up...you can check the ext4 filesystem with a partition program on a regular computer...

    I think I covered that when I reflashed the cm7 I was using - as I checked busybox and it was once again running the CM7 version.

    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.

    Could you do this and pastebin it? (after losing data)

    In a terminal:

    Code:
    su
    logcat -b radio -t 2000 > /sdcard/radio.txt

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

    Code:
    su
    umount /dev/block/mmcblk0p2
    e2fsck -v /dev/block/mmcblk0p2

    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.
