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.
