This bug affects the 4.4 kernel, including the xenial kernel and the lts-xenial kernel in trusty.
As described in the freedesktop bug report, the bug was fixed in the 4.5 kernel with the following commit, http://kernel.ubuntu.com/git/ubuntu/linux.git/commit/?id=92826fcdfc147a7d16766e987c12a9dfe1860c3f The commit was not backported to the 4.4 kernel, and is not present in the xenial kernel. The commit does apply cleanly to the 4.4 kernel and fixes the bug. Please consider applying this commit to the xenial kernel and the lts- xenial kernel in trusty. I'll attach the commit as a patch for the benefit of the bots. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1542939 Title: system freeze after vt switching Status in Linux: Fix Released Status in linux package in Ubuntu: Confirmed Status in Fedora: Unknown Bug description: I'm trying to use the ctrl+alt+1 to switch to a terminal - ok, after switching back by ctrl+alt+7 the system freeze ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-3-generic 4.4.0-3.17 ProcVersionSignature: Ubuntu 4.4.0-3.17-generic 4.4.1 Uname: Linux 4.4.0-3-generic x86_64 ApportVersion: 2.19.4-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: stinger 1644 F.... pulseaudio Date: Sun Feb 7 22:27:42 2016 HibernationDevice: RESUME=UUID=888e93f3-1a7d-4bf8-a00d-cea6a759d03a InstallationDate: Installed on 2015-11-12 (87 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Alpha amd64 (20151112) Lsusb: Bus 002 Device 003: ID 24ae:2000 Bus 002 Device 002: ID 8087:0024 Intel Corp.
