Resetting chip after gpu hang
I have here an Dell XPS 13 9350 2016 (Intel Core i7-6560U ) and have installed
Fedora 23 (GNOME), currently on Kernel 4.4.5-300.fc23.x86_64.
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.
