thanks manfred for helping me out,,,

Facing the same problem
[ 377.856455] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[ 377.866509] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 13484 at 13483, next 13485)

I made following observation:
I am running a MSI H67MA-ED55, i7 2600k, 2.6.38. First time I had this "GPU hung"-issue was after changing the BIOS from 1.4 to 1.5. With 1.4 Ubuntu ran without any problems. Testing 2.6.39 and 3.0rc4 made no difference.

I could imagine this could help a bit in focusing the fault reason if delta between 1.4 and 1.5 is not too big.

Good luck, Peter

i am giving pages and pages of info nobody is taking this seriously....
please help me out guys..............................

Posting the same error message over and over again does not provide additional information.

All your logs indicate that you are facing bug #761065

In that bug report there are hints how that problem can be resolved,
- by issuing echo 1 | sudo tee -a /sys/module/i915/parameters/semaphores (comment #16)
- by changing /etc/default/grub (add i915.semaphores=1 to GRUB_CMDLINE_LINUX_DEFAULT) & update-grub (comment #18)
- by installing higher kernel versions (from different sources) (comment #38)

Have you tried any of these solutions?
Any change with one of these actions?

> i am giving pages and pages of info nobody is taking this seriously....
We do take your problems seriously, but there is not much that can be done except referring you to the relevant bug report and asking you to wait until a solution has been found for that bug, and for the time being instructing you to execute the workarounds described in the bug report.

sorry manfred if i sounded rude.......,
but thisw is my first time using linux and
i never faced these sort of problems in the past with windows..
so its a bit frustrating to me.........
i did comments #16 and comment #18.......
i will tell u if i get any problems..........

i did upgrade kernel version to 2.6.38.10 generic and i am still having problem.....
i even observed something else this flashing mostly occurs when i play a video or play videos through any browsers on internet.
