We are running into this issue with CentOS 7.1 and don't have official support which is why I reached out to the community to see if someone was aware of the work being done on this private bug. I can definitely test out new kernels and provide feedback if that would help and can ask my end users to duplicate the issue on one of our test nodes.

Thanks.

It looks to me like there's work being done on it but no-one can reproduce the
problem on demand and no-one is willing to test possible fixes to get feedback.

It also looks to me like an extremely difficult problem to resolve so as much
help as possible is needed to get to the bottom of it (if in fact it can be
resolved in the short(ish) term).

Are you able to help by providing vmcores or testing kernels?
Have you spoken to RedHat support about it?
