The notebook is frozen right now, I am writing this from my desktop. The desktop is the receiving the netconsole messages. I set the debug options in the kernel build (I still did not test with the boot option intel_iommu=igfx_off) and set the reboot on panic. The notebook needed more than 10 minutes to freeze this time, but the reboot on panic did not work, as it's frozen for a few minutes already (I set in sysctl.conf kernel.panic = 5. I think I found a pattern of the system crash. 1) A GPU hang must happen (for example, the hangs caused by Vulkan); 2) A task with significant video load is closed (watching a video and then closing the media player window, for example); 3) When the focus of the window is changed, the system crashes. It's important to say that with 4.17.19, after the hang I can open and close demanding tasks with no issues. I have attached the netconsole, which seems to not have relevant data again. I will try the boot option later, at least it seems I found some pattern now.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
