 With this patch[DEBUG_LL + earlyprintk],
 I still haven't been able to boot the kernel.
 Is it working on your side.
  
 The commit am using is : a842b5f9ce70e1b738eabb4d719860070180ed1c

I think you will also need the 3630 serial fixes series posted
recently.

I just merged those into omap-fixes-for-linus (and master)
branch(es). Maybe give it a try with at commit
b3c7740a120c8a7775cb63b4d094466da5c01692 + this patch?

  Thanks, I'll pull in those fixes. 
 I believe the mux errors are fixed. Have a look at
 http://dev.omapzoom.org/?p=manju/kernel-omap3-dev.git;a=commit;h=3499f5023ee90dc6ee3868a3147b87fe22a1d9b7

 Patch must have been missed some how.

BTW, I'm still seeing mux errors on zoom3, have not yet
looked into those.
