Until this is patched by other projects, this addition to kernel 4.1 and later may need to be reversed by a patch to allow extra kernel modules to build correctly.

Already this causes ZFSOnLinux some issues, but I have no idea if other modules like Broadcom(wl), nvidia, and other kernel drivers are affected, but do be mindful of Kernels 4.1 or later if you use external modules not normally included with the kernel.

You may need to recreate the patch to reverse out these additions to the code. I ran into a problem with this on a custom build project, so I figured I'd share in case anyone else may have had a problem, or was considering 4.1 or later to use or test.

I've read yours post about the zfs issue. I think the problem is that this file doesn't have a #ifndef macro at the begin of code, which leads to include it more than one time. The patch is not trivial, but you must follow the include tree starting from fs/zfs/zfs/trace.c and check for include guards.

I contacted the project and they said that currently it is being worked on, but patching is the best solution until it is fixed. They directed me to that commit so for now I'm going to work on creating a simple patch for testing purposes.

nvidia binary works fine here
just to note

Thanks Genss. Apparently it's mostly for built-in modules. As long as modules stay external the patch shouldn't be needed.

I cant boot kernels 4.0.x and 4.1.x

My system have a r9 290x crossfire , when system go start return to console and a violet line on left side of monitor.


When unmount one of cards , system start but violet line continue and have only 2d not 3d aceleration. (xf86-video-ati-7.5.0)

Im using slackware current (latest) , using a 4.0.4 config in testing to build a 4.0 kernel


Its posiible have this a related bug?

I try , recompile mesa , radeon driver , libdrm , ... inclusive updating versions but no lucky.

3.18.x works ever well.


I think is related to HDMI CONNECTION.

I've been tempted to upgrade to a 4.1 kernel, but so far have been chugging a long with 3.18.x without issue. Dell Inspiron N4010. Every time I try to get a newer kernel than a LTS, I always have hardware problems.

Well, I found out after a few git pulls and svn clones of modules that it is the kernel and I had to patch it. At least it's a small patch.
