    Interesting. None of my R600 or RadeonSI systems suffer from this issue in either 3.15 or 3.16 -- mesa or mesa-git.

      causing graphics problems with programs hanging or pausing for seconds in KDE, once i saw every desktop program lockup but firefox still worked, it's weird.
      I did a search for "alloc_contig_range test_pages_isolated" in http://lxr.free-electrons.com/search , and I found this: http://lxr.free-electrons.com/source/mm/page_alloc.c
      I have no clue why that would happen. I guess you should google it. (there is, for example, this: http://www.spinics.net/lists/linux-mm/msg70500.html )

        For the record, I experience none of this with 3.15 kernels (don't use 3.16 yet) but I only have APUs : 1 Kaveri, 1 Temash and 2 Brazos.
        Maybe it's related only to discrete cards?

          I see now what you mean, I got the same error message.
          I still cannot run 3.16 without the desktop feeling laggy (e.g., when switching windows), and the last time I ran it, the whole system hung completely... I also had to disable _OSC again, because the bug hasn't been fixed. These things are terrible, IMO...
