Matthias Gehre, as per http://support.lenovo.com/en_US/downloads/default.page? an update is available for your BIOS (1.52). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Thank you for your understanding. ** Tags added: bios-outdated-1.52 needs-upstream-testing regression- potential ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1177775 Title: [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged Status in “linux” package in Ubuntu: Incomplete Bug description: About twice or three times a work day, X freezes, dmesg shows [ 9877.990203] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed...
