The test checks that the object fits into ram (run with --debug to verify that the size is indeed valid). It is probable that the huge-cpu would also fail given enough time to allocate the full object. But it's the spurious oom that kills us: [ 100.627668] 0 pages in swap cache [ 100.627670] Swap cache stats: add 550, delete 550, find 0/0 [ 100.627671] Free swap = 1950564kB [ 100.627673] Total swap = 1952764kB [ 100.627674] 1028502 pages RAM Why are we not pushing others out to swap in get_pages_gtt()?

It impacts all platforms.
That sounds more like a common .config problem.
