I'm testing now with the 6 EIO suppressions you gave me. An interesting note: I just checked on my Ivy Bridge (HD 4000, gen7) system which I was running with the same test: it's still running! It's been 4 days now I think. Pushing 16 (!) 1080p videos of between 100 and 200MB and constantly getting its surfaces destroyed, same as the sandy bridges. This is with all stock debian wheezy packages, except for kernel 3.9-rc8. I have seen the Ivy Bridge lock up, but that was with wheezy's 3.2. Maybe the Ivy Bridges stability in this round is just a fluke though...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
