Description Guillaume Lespinasse 2015-08-31 21:20:02 UTC

The 4.2 kernel has made flush_workqueue() GPL-only, which possibly affects every version of the nvidia-drivers package and causes the following compile error:

FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol 'flush_workqueue'

A patch has already been applied for 4.3 according to this discussion: https://lkml.org/lkml/2015/8/4/802

Here is the build.log http://pastebin.com/hwexnZAP 

Reproducible: Always

Same problem here on ~amd64.

gentoo-sources-4.2.0-r1 contains this patch. Please wait a few hours (as of this writing) for the genpatches and ebuild to hit your mirrors.

Latest patch confirmed fixed, built just fine for me.

Comment 4 Nikolaos Chatzidakis 2015-09-04 20:05:21 UTC

Problem solved for me too with gentoo-sources-4.2.0-r1.
