          Assignee: dri-devel@lists.freedesktop.org
           Summary: i915 Gallium crashes on 2nd generation i3/5/7 card,
                    and a Weston egl client
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: nerdopolis1@verizon.net
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/i915g
           Product: Mesa

It seems that I am getting a crash on egl Wayland clients when I compile mesa
with ilo support.

I have a bt if it's helpful.
I'm realizing I should probably turn off ilo support in my buildscript as it's
too early, but I hope this report is helpful
