Kernel 4.20 is not compatible with zfs-0.7.12. Use linux-4.19, or wait for zfs-0.8.0.

[bunder2015]

Being worked on in #8227

[tonyhutter]

@derek555 this will be fixed in the 0.7.13 release. In the meantime, you can try this patch:
https://github.com/zfsonlinux/zfs/commit/4f981f6ab614a908f912f7dc147b248f96b498a2.patch

Thanks for all the feedback. Downgrading to 4.19 until 0.7.13 comes out.
