It seems the difference comes from configuration.  If I enabled
CONFIG_DEBUG_SPINLOCK, I can run a kernel compiled from current git
tree.  Also, if I used kernel-config in mips-test-0.1 and disabled
CONFIG_DEBUG_SPINLOCK, the kernel stops at the same place.  So I'm
quite sure the option affects qemu's behavior.  But no idea why ...
