Moving to 3.5.1, since we will focus on getting local kdump to work on RHEV-H 7. Adding flag to add release note on this for 3.5.0. Does this bug still exist on the 3.5-7.1 build? (In reply to Fabian Deutsch from comment #4) > Does this bug still exist on the 3.5-7.1 build?

(In reply to Ryan Barry from comment #7) > I can't reproduce this. It works for me on the latest 7.0 image and 7.1 > image. Can you please check permissions and logs on your NFS server? you are right, after reset my nfs server, It works well now.
