As I understand it, this change is wanted as an SRU into 16.04. This will need a test case and a description of regression potential. Knowing nothing about how to guard CPUs, how would we go about reproducing the problem? ** Also affects: util-linux (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: util-linux (Ubuntu Xenial) Status: New => Incomplete ** Changed in: util-linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.
