Might be the common DSP code trying to set NULL clocks on omap2. I've
patched the clock framework to check that:

http://source.mvista.com/git/gitweb.cgi?p=linux-omap-2.6.git;a=commitdiff;h=8fc55a5be4a212efc51a335ddcd5ba066f46de6c

So updating to current git tree should help.

My tree is having this patch and clock fwk is latest as per the git
tree. But the dump seems to coming from debug_mutex_waiter_free(...)
function.

In case you still have this problem, my h4 boots just fine here, BTW.
