System hang with primusrun

I am using the intel modesetting driver while trying to use

optirun -b primus glxgears

but my system instantly hangs after running it. Once I restart my laptop, the journal shows the following.

However, if I do

optirun -b virtualgl glxgears

everything runs as expected. I've tried multiple kernel versions (linux-ck, linux 4.5.4, and linux-lts) all provide the same result.

Re: System hang with primusrun

I have been using i915.enable_execlists=0 as a kernel parameter but it seems that it hasn't been taking effect. As you can see below, enable_execlists is still enabled. I don't have the xf86-video-intel drivers installed and have a Intel 6700hq.

Re: System hang with primusrun

Is your problem possibly related o this bug?

https://github.com/Bumblebee-Project/Bu … -234494238

In my case booting with only  acpi_osi="!Windows 2015" solves the hard lockups.

Re: System hang with primusrun

Thanks for the response. I now have it working but I have no idea how. All I know is I am using the intel driver, not modesetting. Also yes, the acpi_osi="!Windows 2015" came into play later when I ran into freezing on boot.
