Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

Comment 5 Xiao, Hui 2011-03-25 02:56:55 UTC
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

Comment 6 John Villalovos 2011-03-25 16:22:36 UTC
Mark,

Our SugarBay systems at Red Hat should be D stepping machines.

Which Sandy Bridge system are you using for your testing?

Comment 7 Mark Gordon 2011-03-31 19:44:42 UTC
Never mind.  Updated MB/CPU acquired & installed, and the problem can no longer be reproduced.  Closing.
