** Description changed: I wrote about it before - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1391908 Recently I upgraded my system from Xubuntu 14.10 to 15.04 and the bug returned. The problem is that from time to time without an obvious reason the whole system freezes. After that I can reboot the system only via the power button. I have the log after the last freeze (attached). + WORKAROUND: 1. sudo nano /etc/default/grub + 2. There is a line in that: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (like this), replace with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" + Save it (CTRL+O) + 3. sudo update-grub + 4. sudo reboot + ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-26-generic 3.19.0-26.28 ProcVersionSignature: Ubuntu 3.19.0-26.28-generic 3.19.8-ckt4 Uname: Linux 3.19.0-26-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.17.2-0ubuntu1.3 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: yustnip 1512 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: yustnip 1512 F.... pulseaudio CurrentDesktop: XFCE Date: Mon Aug 31 20:11:30 2015 HibernationDevice: RESUME=UUID=8cf5c01a-57c2-49b8-96da-f67a121d8056 InstallationDate: Installed on 2015-08-26 (4 days ago) InstallationMedia: Xubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422.1) Lsusb: - Bus 001 Device 005: ID 04f2:b404 Chicony Electronics Co., Ltd - Bus 001 Device 003: ID 046d:c05a Logitech, Inc.
