Public bug reported:
When using some java applications, like Oracle SQL developer, I get a
GPU hang.. for some seconds the screen becomes black and unresponsive
then it comes back to life.
This issue was not present in Oneiric so it seems a regression.
The laptop is a Dell L702X with an integrated Intel GPU..
this is the lcpci:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA
controller])
Subsystem: Dell Device 0571

Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort-
<MAbort- >SERR- <PERR- INTx-

and this is the error found in dmesg after the hangup:
