A couple more comments: 1. I can't seem to reliably reproduce the scenario I just described in comment #3.
2. AFAIK, we've never made the plumbing work between powerd and NM, such that when a device comes out of S3, it tries to immediately re-connect to Wi-Fi, if it was previously connected. This is kind of moot on the Nexus4, as it currently never goes into S3. 3. While trying to recreate your bug, I'm still occasionally hitting bug #1195787. I just bumped the priority of this bug to Critical. 4. You say you're walking between multiple buildings / wireless domains, can you clarify whether you're roaming between APs with the same SSID, or whether you're connecting to different SSIDs when you move from one building to another? Are they APs open, or secure? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1206405 Title: network-manager using 70%+ CPU on Nexus 4 Status in Touch Preview Images: New Status in “network-manager” package in Ubuntu: New Status in “network-manager” source package in Saucy: New Bug description: This morning after moving around between multiple buildings / wireless domains, NM is now using 70%+ CPU on my Nexus 4 (mako).
