I have not seen anything of interest, and no new messages were printed before the crash took place. The only arguably suspicious line was: [ 1286.800069] perf: interrupt took too long (2502 > 2500), lowering kernel.perf_event_max_sample_rate to 79750 Never the less, I have discovered another important factor during my tests: I decided to look through my BIOS settings again, as I remembered I had left enabled a memory overclock setting called Performance Enhance. In the past when I had a different set of memories, this option caused the exact same freeze when I was watching Youtube (1080p @ 60fps videos). Later on I got new memories, and due to how my clocks are synced I'm running those at an underclocked (therefore more stable) frequency, so I figured I can leave this enabled without problems. The highly erratic probabilities of the freezes threw me off (once it's after 10 minutes, then it's after 2 hours), whereas a crash this obvious would have been all over the bug tracker by now if it was Mesa. After disabling it, I no longer seem to get any immediate system freezes. It will however require more testing to confirm it was that option, so please give me a few more weeks before we close this. If my theory is proven wrong, I'll immediately post a new comment and let everyone know.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
