 Hello,

unfortunately my upgrade from 10.3 to 11-BETA3 caused machine outage.
ESP encrypted IPv6-traffic acauses a immediate crash.
Please see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211486
whereI provided this info:

Unread portion of the kernel message buffer:
Kernel page fault with the following non-sleepable locks held:
