Nothing obvious as no sparc64 specific changes went in lately.
If you use a kernel built with options ALT_BREAK_TO_DEBUGGER,
can you break into the debugger via the alternate break sequence
on the serial console and get backtrace when it hangs? What is
the last known working revision? Can you bisect which revsion
triggers the problem?
