Bug 574358 – sys-kernel/genkernel - please disable FB_NVIDIA, it breaks boot on some hardware

Hello,

I tried to boot a "genkernel all" kernel today on some nvidia hardware, and it failed hard with a green & white screen.  I looked into it, and it's because udev is autoloading nvidiafb before (or instead of?) nouveau.

There is very very close to ZERO situations where nvidiafb is actually wanted by any user.  It is basically always the wrong driver choice.  Could we please disable this in the genkernel default configs?

Thanks!

What architecture are you on?
PPC should be the only place where it's default, and that was just in line with the old PPC defaults.

I just reproduced this on amd64 with:

stage3-amd64-20160211.tar.bz2
gentoo repo timestamped Sat, 13 Feb 2016 18:22:32 +0000

# emerge genkernel
# emerge gentoo-sources
# genkernel --menuconfig all


Kernel sources were gentoo-sources-4.1.15-r1, and I tried with stable genkernel-3.4.52.3 and also 3.4.52.4

Ah, I see what happened, sorry.
Disabled for the next release

I believe the same issue is going on with FB_RADEON, it should really not be enabled ever in the year 2016.  Should I open another bug or not?

yes, new bug for now, since this one is closed already.
