    Do Radeon (kernel module) have new options since 3.17?


    I ask because I got a bug by switching to the kernel 3.17-rc1 a while ago (I rollbacked everything at that time because I needed to use my system and decided to wait a little sooo, I just upgraded to the kernel 3.17-rc4, git mesa, glamor, libdrm, xf86-video-ati, llvm 3.5 and it's back.

    The bug appear with 3.17-rc1 but it stay even if I go back to the kernel 3.16 (after a mesa update), a full rollback of the graphic stack is required...

    == The bug ==

    Not Affected : EVE Online
    Affected : Minecraft

    What append : it work *fine* (maybe at about half the kernel 3.16 FPS) but when the VRAM reach between 260M-300M, the system pause (everything stop) and unpause some time later (it start with small stutters and finish with 5s break...). Once the system is back alive, the VRAM is back to say, 240M and rehang at say, 265M, resume and back to 242M.... hang at 268M... resume at 245M... like that. Only when the VRAM usage is going down.

    I think that the 3.17 got some memory managment improvment, can it be that? If so, it broken.. But I read somewhere last month (can't find it) that we got some option to adjust that.

    The video card is a Radeon 7970 3G
