Bug ID: 222314
Summary: VNET jail panics kernel (arm64)
Product: Base System
Version: 11.1-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: he...@project-fifo.net
Starting a jail with vnets panics the kernel, this is not a duplicate of
#213896 as the patch mentioned there was applied to the kernel in question.
I'm not sure weather or not it is a arm64 related issue or not, it is a arm64
system but the nic used is a normal intel nic.
