Hi, I run OpenBSD 5.6-stable on a Lenovo x201 (patched to the latest errata - 016). I use XFCE as my desktop environment. Every so often when I am moving a window, specifically trying to snap it to the left-hand side of my screen, X freezes up for a few seconds, and the following message is printed to the console:
error: [drm:pid31847:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung error: [drm:pid31847:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung error: [drm:pid31975:i915_reset] *ERROR* GPU hanging too fast, declaring wedged! error: [drm:pid31975:i915_reset] *ERROR* Failed to reset chip. After this occurs, everything continues working, but X is laggy, especially in certain applications. The best fix I've found is to reboot the system. This appears to be the only relevant entry from /var/log/Xorg.0.log: [ 62471.544] (EE) intel(0): Detected a hung GPU, disabling acceleration. If I can provide any further information that might lead to fixing this problem, I will be happy to do so. Thank you! Charlie
