Red Hat Bugzilla – Bug 484620
memory corruption on ATI RS780 integrated GPU with RHEL 5.3 ATI driver
Last modified: 2009-04-21 18:28:23 EDT
Description of problem:
A problem was found upstream where when the -ati driver is used on the RS780 IGP chipset, random memory corruptions could occur and cause disk corruption.
Version-Release number of selected component (if applicable):
Install on an RS780, do stuff in X.
Steps to Reproduce:
Don't corrupt memory.
A fix is in hand from upstream, a one liner.
There is nothing to triage here.
Switching to ASSIGNED so that developers have responsibility to do whatever they want to do with it.
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
Could we get an explanation or example of the symptoms of this corruption?
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.
Quality Engineering Management has reviewed and declined this request. You may
appeal this decision by reopening this request.
This is already fixed in the backport we are doing for 5.4's r500 driver.
so maybe a different closed value?
