Here's a one liner that *doesn't require root* that you can use to test
whether the kernel fix has landed:
unshare -rUn sh -c 'ip link add dummy1 type dummy && ip link set
dummy1 up && ip -6 route add default dev dummy1 && ip -6 rule add table
main suppress_prefixlength 0 && ping -f 1234::1'
Thanks - will wait for kernel fix.

wireguard crashes system shortly after wg-quick down wg0

Yep, confirmed that Eoan is broken. Here's reproduction steps:
root@scw-competent-dirac:~# uname -a
Linux scw-competent-dirac 5.3.0-13-generic #14-Ubuntu SMP Tue Sep 24 02:46:08
UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
root@scw-competent-dirac:~# ip netns add crash
root@scw-competent-dirac:~# ip
Most likely this is related to an invocation to `ip rule` that's being
made, not WireGuard. Take a look at this mailing list post:
