Careful! Bug in Nvidia Drivers 390.48

[Tedel]

Hi,

I upgraded today to kernel 4.17 (which cames along with Nvidia drivers 390.48 and other 2 options) but I got a blank screen and a flickering cursor that never let me log in to console.

After searching for a while, I found this thread on Gentoo forums, which appears to be very related. While our fellow distro masters take a look at the issue, a friendly warning: stick to Nvidia Drivers 390.42.

Hi, has hit me too. I have downgraded to 4.16, but I can't make it work.
Please advice.

Thanks for reporting

please report to https://bugs.sabayon.org/ also and provide some extra infos (hardware and VGA)

[msdobrescu]

Well, I have, but I can't make it work with the old kernel/nvidia drivers. This is outstanding.

[msdobrescu]

Where could I check for the difference between these packages, 390.42 and 390.48?

[msdobrescu]

The behavior of both kernels ends in that flickering prompt now. Is there any possibility to have the cause in the /etc/init.d/nvidia_smi file change between the nvidia userspace versions?

[sabayonino]

/etc/init.d/ directory is part of OpenRC that is no longe mantained.

which nvidia-userspace version do you have installed ?
something like

Code: Select all

$ equo s -qv --installed nvidia-{userspace,drivers}
x11-drivers/nvidia-userspace-396.24
x11-drivers/nvidia-drivers-396.24#4.16.0-sabayon

or

Code: Select all

$ equo q installed -qv nvidia-{userspace,drivers}
x11-drivers/nvidia-userspace-396.24
x11-drivers/nvidia-drivers-396.24#4.16.0-sabayon

I have a 560Ti card, this needs some masking to work, so I use a version less than 396. I've cleaned up the system and managed to install 390.42 and works.
A surprise - is this normal? - is that installing nvidia-drivers did not pull the according nvidia-userspace version. Also, uninstalling nvidia-drivers did not uninstall the corresponding nvidia-userspace version.
Asking to install nvidia-drivers, without specifying a version, like 4.16, pulled the latest kernel and nvidia-drivers again, i.e. 4.17.

I know init.d should not be used anymore, but that part being changed makes me think if something inside did the same for systemd too, that breaks the whole thing after installing 4.16 only again. That until I remove the 4.17 nvidia-userspace.

I am booting kernel 4.14 and Nvidia drivers 390.42. Those should still be in sabayon-weekly repository.

As for what is happening, version 390.48 of the driver looks for a routine that is not in use (swiotlb_map_sg_attrs). As it doesn't find it, it fails. There is already a patch, so I guess it is just a matter of waiting until we get a new driver version or the patch is distributed in Gentoo.
