I'm seeing a large number of allocation errors originating from the Mellanox IB

Just to make sure, mlx4 works fine on this small (...) system with 4.1
and 4.2-rc1 breaks, or 4.2-rc1 is the 1st time you're trying that
config?
I'll let Alex comment on that, he did some testing on that.
I started seeing this on a 4.1-rc8 kernel, so it's been around for a
little while. It may have been around before 4.1-rc8, but I haven't run
any kernels older than that on the big machine for some time.
To make sure I am correctly following, on 4.1-rc8 you also see
something, right?
Yes, that's correct.
are these the same messages or different ones? if the latter send to us.
We see the same exact messages on 4.1-rc8.
Hi,
We don't recall getting those error with 32cpu machines, but we'll try
to reproduce this issue.

Thanks for looking into this!
