[Bug 1602737] Re: PCI RoCE Interface could not be renamed from default name with link file

Tue Sep 13 14:57:42 UTC 2016

Quickly clarified - that was running on Xenial + kernel mainline ppa.

That means it is nothing in e.g. udev in userspace.

Barbara will try to test 4.5, 4.6 quickly as well.
Only if also 4.5 mainline is good too she will test 4.4 from mainline as well (to check if a diff to the xenial 4.4 is causing the issue).

Then I expect it is up to recreating and bisecting on our side?

  for a qeth network interface it works fine 
  I will attach sosreport as well to the Bugzilla
