even with 16GB of ram in APL the following tests keeps failing :

looks like that is something wrong in the test itself of the test needs much
more memory ?

Guys have you actually looked at the following line ?
Aperture size is 268435456 MiB -- That is 256 TiB !!!
That's rather impossible amount if you ask me. So there's either a bug in IGT's
gem_aperture_size() or one of the two ioctls (I915_GEM_CONTEXT_GETPARAM
I915_GEM_GET_APERTURE) that it uses.
With a couple of print statements you should be able to quickly track the exact
offender. Good luck !

Yes, we saw it. The bug is reported to IGT (not to DRM/Intel). We propose the
test should skip.
I just checked on our IVB platform with 32 GB of memory. Looks like we would
need now 2 TB.

It is correct. The GTT size is 1<<48 bytes.

Why? The test only allocates enough to fill RAM and then tests that the buffers
are evicted for memory pressure. The messages are nothing to do with this test,
just spam.
