Folks, re-sending this because the first try never hit the list - perhaps
mail with attachments are silently dropped or held for manual moderation?
I'd originally attached an image of the stack trace.  I'll host it and
reply to this with a  URL link in case that would also result in a drop or
moderation.



Anyhow:

In testing the new RHEL 7.5 beta, we've discovered that hosts using AFS
fail to boot after the upgrade, with Openafs 1.6.22.1 installed.

We are wondering if some of the non-guaranteed kernel ABIs that OpenAFS
uses might have changed with the latest kernel provided in RHEL 7.

I've attached a picture of the trace.

Anyone else kicking the tires on the new RHEL yet?

Thanks!
