We seem to have neglected the bug a bit, apologies. Aslan Xie, since There were improvements pushed in kernel that will benefit to your system, so please re-test with latest kernel and mark as REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log) and RESOLVED/* if you cannot reproduce.
