Just loading carp kernel module is enough to panic it:

FreeBSD router.bsdrp.net 12.0-ALPHA2 FreeBSD 12.0-ALPHA2 r338100M
i386 [root@router]~# kldload carp
Fatal trap 12: page fault while in kernel mode
How many vnets were already instantiated at the time of kldloading
carp? Does the panic ocur with no (non-default) vnets instantiated?
Hi,
None VNET were instantiated: Just start the latest 12-i386 image (
https://download.freebsd.org/ftp/snapshots/VM-IMAGES/12.0-CURRENT/i386/Latest/)
on a VM, and once logged as root enter 'kldload carp' to trigger a
panic.
From the backtrace it seems like VNET_PCPUSTAT_SYSINIT() or the kernel
linker, or possible pcpu things. People have recently been touching
almost all of this :(
Do you have a last-good revision?
