Hm, Imre's fix to sanitize the adjusted mode might help here, can you please retest on latest -nightly? Test on latest -nightly kernel. This issue goes away. Close it. Verified.Fixed. (In reply to comment #4) > Sorry. It doesn't fix on GM45, Report Bug 69791. Actually filing a new bug report was the right thing to do. This bug here is different from bug 69791, and this bug here is indeed fixed whereas the new one is a different issue (although very similar backtrace). Closing verified+fixed. |
