To build on Andreas's comments - it is well understood that 2.10.x will not
work with a 4.19 kernel. Newer kernel support was a primary driving factor into
switching to 2.12.x for the LTS release branch. Once the work has completed on
master we will backport it to b2_12.

These problems may relate to using GCC8, which has a lot of new checks
that cause old code to break. You could try installing an older GCC,
but that may not create modules compatible with your kernel.
The GCC8 issues are being fixed on master, so you might want to try this
again, but at the same time, master is still undergoing a lot of landings
for the 2.13 release and not what I'd recommend for using in production
until the final 2.13.0 release is finished.
If you are using Debian, I'd suggest to download the Ubuntu 18.04 LTS
kernel, which is 4.15 based. This is built on a regular basis.
Cheers, Andreas
