LL/SC are undefined on uncached memory. Implementers are free to keep the instructions working the same way as on cached memory, but are not required to do so and your chip may be an example. Of course the reason of the hang you see may be different, but this is one plausible explanation. I wouldn't trust a kernel running with CONFIG_MIPS_UNCACHED enabled -- it is merely a debugging hack.
