This is a problem on an HP mini 210-1010nr running i915 driver. My dmesg contains the "Hangcheck timer elapsed" message as well as the "i915_do_wait_request returns -5" message. In addition (and this may or may not be important) I get the message [drm] Big FUFO is enabled" repeated several times around when the happens.
My report differs from the previous reports, though, in that the screen does not totally hang. Instead, X restarts into "recovery" mode. Virtual terminal still work, so I am able to do Ctrl-F1, look at dmesg, etc. Subsequent attempts to restart X fail. I didn't have this problem running fully updated Karmic on the same machine. This started happening with Lucid, which I just installed. It is pretty much a deal-breaker, and it renders the system unusable. -- display freezes, [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
