            Bug ID: 89029
           Summary: System hangs and screen powers down and back up when
                    setting "sky" texture on a surface in
                    Tesseract/OctaForge
           Product: Mesa
           Version: 10.4
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org

This is a bug that only happens in Tesseract / OctaForge (maybe affects other
engines that I didn't test), but when I set a block's face to sky tex, my whole
system hangs for about 15 seconds, then the screen goes to black, powers off,
powers back on and the display is back, until it hangs entirely (the screen
doesn't go blank this time). Using ATI Mobility Radeon HD5470 on an Acer Aspire
5742G-7353, OpenSUSE Tumbleweed. I couldn't get a backtrace due to my system
being unrecoverable after the event. REISUB works, obviously.
