As soon I open Chrome or Firefox and let’s say open YouTube after few second whole laptop will hang, totally unresponsible. Need to press Power ON button for few seconds to power of the device. Once I was able to get log and its attached. I added "intel_iommu=igfx_off" to /etc/default/grub and regenerated GRUB ( grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg) but it does not solve the problem here. If any more info is needed I would be glad to provide them to you. I hope I will be able to use my new Notebook without issue.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
