Bug ID: 94242 Summary: [radeonsi] Crash while running Fedora mock tool for prompting root (gtksu) Product: Mesa Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: shawn.starr@rogers.com QA Contact: dri-devel@lists.freedesktop.org
Kernel: 4.5.0-0.rc4.git2.2.fc24.x86_64 MESA: git master, Feb 19-20th builds LLVM: trunk 3.9, Feb 19-20th builds DDX:
For some reason, X crashes with radeonsi triggering VM fault, when in GNOME or KDE environments:
If you open up a shell console (gnome-terminal, konsole etc), run mock as non-root, as soon as an attempt to prompt for root happens (with gtksu) it locks up system.
