Ooops, it seems, that my previous message with uncompressed logs was a little too big. I'm resending it with compressed logs, even though they will be probably discarded in the archive as "unhandled content"

After I've switched on debugging (booted with drm.debug=0x06 and mounted "sudo mount -t debugfs debugfs /sys/kernel/debug" the probability of the error decreased. However after 2 hours or work it happened again. There was nothing specific performed on the machine. OK. This time I had the iceweasel window in the background, and was running an application under wine emulator, but previously the same problem occured when I had only two gnome-terminals opened and iceweasel. The problem may be associated with switching of active window in X or with switching of active tab in iceweasel (i.e. with activity related to massive change of displayed contents). I attach the output of the i915_error_state.txt, the log of X server. Sorry for big uncompressed files, but when I compressed them previously, I saw that they were ignored by archive website as "unhandled content".

I was not able to send the glxinfo, as after login via ssh to the hung machine and running "DISPLAY=:0 glxinfo" the command hung and didn't display anything.
I have also attached the output of "intel_gpu_dump" command. -- HTH & Regards, Wojtek Zabolotny
