Hi, We have verified the graphic feature of: [1] PCI:*(0:0:2:0) 8086:0102:8086:2210 Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller rev 9 on Sugar Bay (Sandy Bridge D1, Cougar Point B0) with image 2.6.32-118.el6.x86_64 [2] PCI:*(0:0:2:0) 8086:0116:17aa:3975 Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller rev 9 on Huron River Production "Lenovo v470G-ISE" with image 2.6.32-118.el6.i686 no such issue occured. From the log you seems using Integrated Graphics Controller rev 4? Can you tell more infor about: [1] What platform are you using? [2] What's the Processor/Chipset stepping? Thanks

Hi, we recommend to use the newer machine for all the tests. Could you please try to find a Sandy Bridge D stepping machine instead of C? :-) Thanks
Mark, Our SugarBay systems at Red Hat should be D stepping machines. Which Sandy Bridge system are you using for your testing?
Never mind. Updated MB/CPU acquired & installed, and the problem can no longer be reproduced. Closing.
