--- Comment #25 from lbdkm...@sharklasers.com --- Yes, this, aparently, only happens in dual AMD graphics laptops (with llano)... and I found a workaround: you have to disable the second (discrete) GPU: echo OFF > /sys/kernel/debug/vgaswitcheroo/switch and it will not crash anymore... Sadly, vgaswitcheroo throws a big warning in dmesg: http://pastebin.com/rXj8rrZa (I'm using kernel 3.11.0-6 from ubuntu's proposed repos) , after which "/sys/kernel/debug/vgaswitcheroo/" disappears completely and I'm not able to use the dGPU until the next boot. I will have to report this.. dunno where though. (and also, I always get a black screen after resume from suspend to RAM). as I said before, the patch "helped", i.e., made it harder to crash, but apps (glxgears, vlc, mplayer + gl) will crash nonetheless. I hope this helps. And I want to thank the devs for their great job with the radeon FOSS driver! -- You are receiving this mail because: You are the assignee for the bug.
