Description Red 2019-03-14 00:20:13 UTC

I have a really old laptop (Latitude E6410) with an old video card (NVIDIA Corporation GT218M [NVS 3100M] rev a2) which requires nvidia-drivers-340.107.

No problems with kernel 4.14, but crashes with 4.19 at boot. X does not start, the computer goes to a blank screen and freezes, requiring an improper shutdown.

A similar bug was recently reported (and fixed upstream) for the 390 series x11-drivers/nvidia-drivers (Bug 658748). I was told to file a separate bug for 340.107.

Attached are the relevant parts of /var/log/messages.

Reproducible: Always

Steps to Reproduce:
1. Upgrade sys-kernel/gentoo-sources from the 4.14 series to the 4.19 series, per https://wiki.gentoo.org/wiki/Kernel/Upgrade.
2. emerge @module-rebuild to rebuild =x11-drivers/nvidia-drivers-340.107
3. Make the initramfs with genkernel, update grub
4. Restart into a 4.19 series kernel.
Actual Results:  
Crash, X does not start

Expected Results:  
Continue boot and start X

I would not have asked you to file a bug report. Upstream does not support newer kernels for the 340 series (yet).
