On closer examination the suspend issue that I was seeing was not related to the 1.2.6-0ubuntu0.16.04.1 networkmanager upgrade but a bios upgrade I performed a few days earlier. The forced reboot only occurred when suspending while powered and resuming on battery after unplugging the laptop, which is why I hadn't noticed earlier. After downgrading the bios and reinstalling the networkmanager update everything is working fine now.
Apologies for the false alarm. For anyone interested, the system is an XPS 9350 and the offending bios upgrade was 1.4.13 (reverting back to 1.4.12 fixed the issue). ** Tags removed: verification-failed-xenial ** Tags added: verification-done-xenial -- 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/1645698 Title: [SRU] Upgrade network-manager to latest point release Status in OEM Priority Project: Triaged Status in network-manager package in Ubuntu: Fix Released Status in network-manager source package in Xenial: Fix Committed Status in network-manager source package in Yakkety: Fix Released Bug description: [Impact] This SRU would try to have the latest well-tested upstream point release (1.2.6) of 1.2.x land in Xenial, which is the successor of the current 1.2.2 version, fixing quite some bugs that's suitable to land in the stable branch. https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/NEWS?h=nm-1-2 [Test Case] After installing the updated version, users should be able to avoid some mem leaks in some cases and have generally improved DNS related experiences. Also, as this is a general point release update, cases described in https://wiki.ubuntu.com/NetworkManager/DistroTesting should be used for smoke testing. [Regression Potential] This is a bug/regression fix for 1.2.2 and 1.2.4, which is quite complete. [Other Info] The first attempt at SRUing this to xenial was for 1.2.4 but it failed verification. This second attempt matches yakkety with 1.2.6. Parallel building was enabled in xenial to keep the diff between xenial and yakkety minimal since they are basically in sync now. Parallel building was enabled in the yakkety package in May 2016 so it's been working fine for a while. needed by: lp #1647283 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1645698/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
