Public bug reported: System is not running stable, it crashes (freezes) sooner or later. Sometimes with virtual console on screen, saying
“not syncing: fatal exception in interrupt drm_kms_helper:: panic occurred, switching back to text console” - sometimes without console appearing. No more input possible (no sysrq), just hard reset. Apparently this is caused by i915 driver. It always happens with applications with a bit higher graphics performance requirements, e.g. watching DVB-T-TV in a little me-tv- or vlc-window and browsing the Internet at the same time. Initially core temperature and fan speed rise, and then follows the exitus follows. Same experience on Xubuntu 14.04 and Kubuntu 14.04. The reason why i file this against Utopic is that i have altered my Trusty-Systems with Intel Drivers from 01.org (see below). The following attempts did not improve the thing: Trying “Intel Graphics Installer” from 01.org 1.0.7 within the Trusty Systems. Trying (alone and with Intel Drivers) Mainline Kernel 3.18.1. But of course initally with regular Utopic 3.16. It may be of interest that on the very same machine the OS “Siduction” (Debian Unstable Rolling Release) runs without any problems or concerns (currently Kernel 3.18 and xorg-packages from Debian Sid branch). The computer is the Asus "Vivopc VM-60", CPU i5-3337U. ~$ lspci -nnk | grep -i vga -A2 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) Subsystem: ASUSTeK Computer Inc.
