Kernel – 4.14.10 Still breaks NVIDIA!

Just updated the test system to Kernel 4.14.10, and was ‘somewhat dismayed‘ – to put it politely – that the NVIDIA breakage introduced in 4.14.9 is still there!

So… the 4.14.9 patch still applies, and fixes the problem (see http://rglinuxtech.com/?p=2168 ):

Its not as if the kernel devs weren’t told…  http://lkml.iu.edu/hypermail/linux/kernel/1712.3/02196.html

Oh well, maybe in 4.14.11??

Kernel – 4.14.10 Still breaks NVIDIA! — 5 Comments

  1. Use 387.34? Kernel devs will never care about closed source driver support, so why you would think it is them who need to do something is beyond me.

    • @Henk Koekwaus. Of course, I don’t think that! But.. there have been several occasions where changes affecting NVIDIA – usually around GPL licence changes – _have_ been reverted – eventually.

  2. I had strange case with 4.14.11 on ryzen 7 1800x with opensuse tumbleweed (I use nvidia 340.104 legacy driver)
    The first problem “init 3” was stalling
    The second was for patched driver, no successful compilation; also get stack somewhere after “unified memory” stuff.
    I passed boot parameter “nopti” and tried it and now its ok!

    • @Kemal, I think that some of the AMD processors were still flagged for PTI in 4.14.11, and this should have been corrected in 4.14.12..
      RG.
