these failures are to be expected on 4.15 and older kernels. they were split from the large vmx test, this is not a blocker, removing the tag.

We will continue to run these tests on the 4.15 and older kernels, to ensure that the kernel does not crash or panic, etc. There is no plan to stop running them. We just know they will fail

For B-aws (4.15.0-1093.99) this cycle, it's not failing anymore
Same thing applies to Trusty / Xenial Azure (4.15.0-1106.118~14.04.1 / 4.15.0-1106.118~16.04.1)

Probably fixed by the fix in 1872401
