Nouveau module results in total lockups without any dmesg trace on a NP900X5N Kaby Lake machine

Hi Ben, David and Daniel , First of all happy new year. Based on advice of Greg K-H herewith a mail about a number of Nouveau issues with my laptop. I installed various Kali linux versions up to Linux 4.20.0-rc7 (downloaded, compiled and installed) on a Samsung NP900X5N laptop and have an issue with the driver after loading. My configuration: - i7 7500 - 16 gb / 256 gb ssd - nvidia 940MX (for 3D graphics) When I enable loading of the nouveau module for my Nvidia 3D card I get three MMIO faults: [ 35.984104] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6013d4 [ IBUS ] [ 35.997510] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ] [ 37.551790] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 619444 [ IBUS ] I see currenty varous discussions on bugzilla: (as summarized by Bruno Pagani) https://bugs.freedesktop.org/show_bug.cgi?id=100423. But I do not see any confirmed solutions on the MMIO faults. The module is loaded but X server cannot run in framebuffer mode. I assume that the module does not provide any video memory to X to run in graphics mode. First of all I would like to understand what the faults impose. And I also would like to help you providing testing to fix the errors. Many thanks for your kind support. -- Met vriendelijke groet, *dr.
