Does it even boot for you?  On my side, it stops at the point below.

[    1.600867] ci_hdrc ci_hdrc.0: doesn't support gadget
[    1.606282] ci_hdrc ci_hdrc.0: EHCI Host Controller

You must have both patches below applied.

 1) ARM: mxs_defconfig: Build CONFIG_INPUT_EVDEV as built-in
 2) ARM: dts: imx28-evk: Enable touchscreen support

I found that applying either one of the two without applying the other
will result in a broken audio playback.

That said, my mxs/soc branch gets a broken audio playback, and
next-20130322 should be the same case, because both have the second
patch not applied.

I'm going to drop CONFIG_INPUT_EVDEV patch from my mxs/soc branch, and
will not apply either of the two until the root cause of the broken
audio playback gets identified.
