:(
Looks like a "complain to nvidia" problem or you could work around it by hacking your own kernel that will never be accepted upstream...

OK: I see, for now I leave kernel untouched and I hack modpost just to work around particular nvidia GPL issue. |

Hm, nvidia-drivers-370.23 build and works here fine with gentoo-sources:4.7.1 | Code: | equery b nvidia-drm.ko
* Searching for nvidia-drm.ko ...
x11-drivers/nvidia-drivers-370.23 (/lib/modules/4.7.1-gentoo/video/nvidia-drm.ko) |
Have you old unneeded patches in /etc/portage/patches/x11-drivers/nvidia-drivers/ ? |

| Try setting CONFIG_DEBUG_MUTEXES=n in your kernel config and recompiling. This fixed it for me here. Perhaps it's a kernel bug that this symbol is flagged GPL only when debugging is enabled? Or maybe it doesn't exist otherwise. Anyway this is the quick and simple fix, assuming nothing else you use requires mutex debugging to be enabled. |

I found a fix for the 367.35 version and works fine with Kernel 4.7:
Just apply this patch:

Worked for me.
Only functionality loss now is that this kernel breaks the acpi event for toggle touchpad functionality. |

A workaround:
Patch the kernel with this, or modify the respective file:
http://pastebin.com/mTtDpN2K
| Code: |
--- a/kernel/locking/mutex-debug.c 2016-01-10 20:01:32.000000000 -0300
+++ b/kernel/locking/mutex-debug.c 2016-09-11 02:38:11.331048350 -0300
@@ -117,4 +117,4 @@
lock->magic = NULL;
}
-EXPORT_SYMBOL_GPL(mutex_destroy);
+EXPORT_SYMBOL(mutex_destroy);
|
Then rebuild the kernel and then try to install nvidia-drivers 370.28. Works for me. |

Answer by myself: I didn't find it, but I disabled "kernel hacking -> Kernel debugging" (no idea if it was enabled by default) and that made it

In make menuconfig (or genkernel --menuconfig) you can press "/" then "DEBUG_MUTEXES" to search for the option, then "1" to go to the result and change it. |

| This happened to me, too, when I decided to be lazy for once and use a generic kernel instead of configuring it for myself. Thanks! |
