--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Does removing CONFIG_DEBUG_WW_MUTEX_SLOWPATH from the list of options enabled
fix things? This option randomly injects failures into ww mutexes (now used for
ttm)... dunno if that would be enough to cause your issues or not, but
definitely worth trying without it.
