Created attachment 359852 [details] xorg.conf file I've also included the xorg.conf used. This is the default file that was generated during install. I saw the Xorg.0.log file mentioned no Monitor section being defined. But even if I do specify one, the Backtrace still occurs.
Created attachment 361323 [details] Proposed patch This patch seems to fix the issue.
I've also noticed this issue, and attached my logs on bug 524242 -- I didn't see this one while searching before. I'll try the proposed patch and see how it goes.
(In reply to comment #7) > I've also noticed this issue, and attached my logs on bug 524242 -- I didn't > see this one while searching before. Yes, bug 524242 should be marked as a dup of this one indeed, it is the same chipset/symptoms/backtrace.
Can you make a package with this patch? Or I can wait for Doug to test it first. Thanks.
I've actually gone ahead and tested already--works just fine. I did build up an RPM in the process for our use internally, but I'd probably be more apt to let the Red Hat engineers provide a package.
I came across this issue today as well. Will try to test the patch.
I built an RPM with the patch, and can confirm that it corrects the problem. Thanks.
Yeah it looks like we got half a backport from upstream, the code to add/remove i2c buses around the crt detect, but not the new crt edid get function from upstream. Either this patch or backporting the rest of the CRT detct code should fix the issue.

Server aborting With this update, this issue has been resolved.
