For those who struggle/getting the crash from "realtek-rtl88xxau-dkms", please wait for the package to be updated in repo or build manually (if you really need those drivers working right away) until the package get updated in the future.

The "new" repo with additional device support, kernel v4.11 & v4.12 support is found @

An additional note, for building manually don't forget installing the "linux-headers" package before building too.
