Comment 2 Chris Wilson 2019-09-10 10:32:11 UTC 
The underlying issue here is bug 108686 (direct reclaim failure under swap conditions). The only slight conundrum is that gem_create/create-clear strives to avoid running into swap in the first place. But I can simply blame java for that and focus on the kernel problem.
