There is nothing to triage here.

Switching to ASSIGNED so that developers have responsibility to do whatever they want to do with it.
Comment 2 RHEL Product and Program Management 2009-03-11 11:19:07 EDT
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
Comment 3 Cameron Meadors 2009-03-31 13:29:40 EDT
Could we get an explanation or example of the symptoms of this corruption?
Comment 4 Dave Airlie 2009-03-31 19:20:33 EDT
It was reported upstream as a memory corruption in the Fedora driver, wierd segfaults and disk errors when X was running on these chipsets.

I don't have a simple reproducer, I just tracked it down by inspection.
Comment 6 RHEL Product and Program Management 2009-04-21 11:25:45 EDT
Quality Engineering Management has reviewed and declined this request.  You may
appeal this decision by reopening this request.
Comment 7 Dave Airlie 2009-04-21 18:28:23 EDT
This is already fixed in the backport we are doing for 5.4's r500 driver.

so maybe a different closed value?
