Can Red Hat confirm if this patch is going to be in U4 ? The patch looks very safe to me. It will be committed to our CVS soon, and slated for RHEL3 U4. The similar patch for RHEL 2.1 will be committed at the same time for the next 2.1 update too. I'll update the status of the report once it's commited to CVS also. Thanks for the patch Hui. Hui) Can you confirm also if this is commited to Xorg CVS for the upcoming 6.8.0 release? If it isn't, a bug should be filed upstream there with a udiff that applies to CVS head, and CC myself and Kevin on it, as the release is nearing quickly. Thanks again! It's in current xorg CVS head and will be in 6.8.0 release. Thanks for merging this to your CVS. No problem Hui! Thanks again. Patch updated in 4.3.0-69.EL build, which will be released as erratum within the next few weeks. Setting status to "ERRATA" for pending erratum release.
