Hmmm. I typically figure these out by looking at the code, and adding
instrumentation (via ftrace, printk .. or whatever you prefer).

What set of kernels have you tried ? Rather than debugging "everything",
bounding the problem is always a good idea.

It could be the userspace options and build flags, mismatched with the
kernel if you can't execute anything in userspace.

And finally, check to see if KDB works on the platform, if it does,
you might be able to use the in kernel debugger to get more hints.
