Hi All

I am not sure if this is the correct mailing list -

I upgraded my Dell Latitude D630 Laptop to 11.4 from 10

It hangs with below errors -

Looks like you've run into this bug:
<https://bugs.launchpad.net/ubuntu/+source/linux/+bug/507504>
[display freezes, [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer
elapsed... GPU hung ]

More recent:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/736170
[[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung]

and another:
<https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/737972>
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung ]
Someone really ought to tie those together... I'd add your comments to
737972 and point out the other bugs in your comments. And of course you
can try to find more:
