After a zypper dup then reboot, my laptop hanged at boot time and had the following error:
drm:fw_domains_get [i915] *ERROR* render: timed out waiting for forcewake ack request.
Do you guys know what does that mean?
I tried to boot using kernel parameter nomodeset. The error above went away but it still hanged there.
I tried using acpi=off and it successfully logged me in. I re-installed xf86-video-intel, all xorg-x11*, and even Mesa packages (although I don’t quite know what’s that for). Then I reboot again without acpi=off and it still hanged there and same error.
So my question is, what exactly does this i915 refer to? Intel GPU? Shouldn’t its driver be xf86-video-intel? I re-installed it many times and thought the error would go away but it did not.
What do you guys think? Recently I got many Intel errors, which I thought would be very unlikely. I got rid of some, but others like this one I just don’t know what it is.
Btw, I have bumblebee and bbswitch and already turned off Nvidia card. As far as I know, this method works properly, based on the opensuse tutorial.
Thank you very much!
