You didn't mention your kernel version, so I assume you're using the
latest stable hardened-sources. The panic is a known issue for 4.8,
caused by a combination of bugs in the upstream kernel and the
grsecurity patch. You can resolve it by either downgrading to 4.7 or
upgrading to 4.9.

See this thread[0] for more information.
