In order to fix random hangs on MT7621, we've been selecting WEAK_REORDERING_BEYOND_LLSC for years [1]. However, these random hangs have been most likely caused by an oversight in the MIPS implementation of the kernel memory consistency model, which has already been fixed for some time (and backported to stable) [2].
