This means you are running your heavy load with lockdep enabled. I
can't see how it directly causes your issues, but it will slow anything
down to almost a grinding halt on systems with more than say two cores.
Can you run with CONFIG_DEBUG_LOCK_ALLOC / and CONFIG_PROVE_LOCKING
disabled/ It might be worth if you have other really heavy debugging
options enabled, too.
