            Bug ID: 93458
           Summary: page allocation failure: order:5, mode:0x240c0c0
           Product: xorg
           Version: 7.7 (2012.06)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: zcalusic-7aYyyD3GOf7R7s880joybQ@public.gmane.org

Kernel 4.4.0-rc5+, G94. The below failed allocation happens pretty often, with
various applications like Xorg, iceweasel, icedove, mplayer, qpdfview. The
order 5 is a pretty big contiguous allocation, if memory is fragmented the
linux kernel will give up pretty fast (if the order is above 3, IIRC). Maybe
somewhere kmalloc should be replaced with vmalloc? Didn't see any of these
errors in kernel 4.2.0.
