I am trying to run my linux media sdk application on a "Ivybridge" cpu, specifically the xeon E3-1245V2. We are using the intel S1200KPR server motherboard.
Basically my question is, do you see any incompatibilities with this setup? Our application works great on the haswell i7-4770s, on a desktop board.
On the E3-1245V2, what happens is that I can run one instance of the application. But when I try to run a second (or more) instances, I start seeing errors in the dmesg that say:
[ 34.886936] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[ 34.887659] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[ 42.888055] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
The hangcheck error is repeated over and over.
I am running in ubuntu 12.04 with the recommended 3.8.0-23-generic kernel.
If the i915_error_state file would be helpful, I can post it. It is very large..
