** Tags added: apport-collected natty running-unity ** Description changed: I just installed a fresh Natty on my brand new Thinkpad X220. Everything works quite fine, except for that I'm experiencing "micro hangs" in the X server: Every few seconds, the system seems to hang for about 0.5-1 seconds, but then resumes normal operation, filling in typed characters from the buffer or completing the current mouse movement. Whenever this phenomenon occurs, I get the following line in /var/log/syslog: Jun 8 17:36:31 tango kernel: [19380.993923] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 7717165, at 7717165], missed IRQ?
