            Bug ID: 66281
           Summary: DRI_PRIME=1 glxinfo crashes and causes session to
                    restart
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.13 rc2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: mortem.dei at gmail.com
        Regression: No

I have a new laptop but the secondary GPU can't be accessed by the system
(neither with Nouveau nor bumblebee). With the kernel 3.12 the output of xrandr
didn't even show the card, but with the new one I do get the following output:


xrandr --listproviders

Providers: number : 2
Provider 0: id: 0x66 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs:
4 outputs: 3 associated providers: 1 name:Intel
Provider 1: id: 0x3f cap: 0x5, Source Output, Source Offload crtcs: 0 outputs:
0 associated providers: 1 name:nouveau

However, when I try to run anything with DRI_PRIME=1 glxinfo the system crashes
and I have to restart the session.
