Created attachment 132127 [details] dmesg output Laptop: Dell XPS 15 9560 This bug happens in 4.11.6 kernel, but I tried 4.12_rc6 - stil the same. Then, when I try to start X, it returns me error: BUG: soft lockup - CPU#3 stuck for 23s! Will add the kernel stacktrace and log for 4.12_rc6 bit later today.
FYI, if you want to blacklist Nouveau (or any module), the syntax is `modprobe.blacklist=nouveau`. You can also disable Nouveau by setting `nouveau.modeset=0`. Hardware acceleration support for GP10x cards is coming with 4.12, so it is expected that <4.12 fails to create the kernel channel. There is some initial acceleration support for GP107 in 4.12, but I don’t whether it needs more work to be usable, or not.

Hi Anton, There's a bug report already (bz#100228) that tracks support for the GP107/nv137 chip. Take a look there for the software packages that you will need. As outlined by Ilia Mirkin, you will need at minimum (numbers are the mainline version or Debian packages, not sure how Gentoo handles these): Linux kernel >= 4.12 xf86-video-nouveau >= 1.0.15 linux-firmware >= 1.165 mesa git This stack provides *preliminary* support for GP10x. However, additionally for your XPS 9560 which uses the GP107, you will need to get around a current ACPI bug. There are reports of this ACPI bug affecting the graphics card regardless of whether you use the proprietary nvidia driver or the open source nouveau driver. So it's not a nouveau problem, but is causing the issues with soft lockups. You need to set acpi_rev_override=1 (any positive non-zero number works) in your GRUB boot line. The kernel must have been built with CONFIG_ACPI_REV_OVERRIDE_POSSIBLE. https://github.com/Bumblebee-Project/bbswitch/issues/148#issuecomment-283639754 *** This bug has been marked as a duplicate of bug 100228 ***
