Zfs module not loaded with grsec enabled kernel

Installed linux-grsec from community repos and compiled zfs-git from Aur with dkms.
zfs packages compiled successfully and modules were created. Re ran mkinitcpio -p linux to make sure hooks were processed.
However during the boot zfs module was not loaded.

Journalctl revealed following lines:

Help please!

There's your reason for the module load failure. Searching on the “zavl” message, DuckDuckGo gives https://github.com/zfsonlinux/zfs/issues/4649 as the first hit.
