It'd be tough.  I've been playing with arm vendor kernels lately
(probably the same codebase) and doing some filesystem backporting...
it's possible but not for the faint-hearted.

You did sysrq-t; if sysrq-w is supported in the kernel it will give you
only the tasks in blocked state, which may show a deadlock more clearly?
