Description Victor Petrenko 2016-01-14 15:41:00 UTC

When trying to use my discrete video card whole system freezes after couple of seconds and doesn't react on anything. I've tried to have a delayed killall -9 running in the background like "sleep 60 && killall -9 glmark2 &" but it seems to be never run or having no effect. Only hard reset helps. 

Have Intel HD4000 + muxless Radeon 7730M

[g0ga@work ~]✘ xrandr --setprovideroffloadsink radeon Intel
[g0ga@work ~]✘ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD CAPE VERDE (DRM 2.43.0, LLVM 3.7.0)


doesn't matter what to run, everything is going to die. kernel 4.3.3 + xorg 1.18.0, archlinux distribution, most recent at time of writing this post. Please let me know how to provide more data for you being able to debug this. 

Thanks,
Victor

Does booting with:
radeon.runpm=0
on the kernel command line in grub help?

Nope. Same behavior. A couple of seconds i can see things running but then everything becomes very slow and in another second whole system freezes. Funny thing that mouse cursor still works (freezes from time to time but movable), but can't switch to plain terminal by Ctrl+Alt+FX anymore or to do any other action. Another thing that fan starts running with crazy speed, so it means that in the background something happens and makes videocard/processor rather loaded.

Please attach your dmesg output when after it hangs.
