maintainer-feedback:
Bug 230460: emulators/virtualbox-ose panic on CURRENT
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230460



--- Description ---
Virtualbox is causing a kernel panic during VM start.

I'm using a recent CURRENT:
$ uname -a
FreeBSD capeta 12.0-CURRENT FreeBSD 12.0-CURRENT #10 r337378M: Mon Aug	6
11:06:26 -03 2018    
danilo at capeta:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG	amd64

I'm not using the binary module, I built it from ports.

The system panics immediately and doesn't drop me to the debugger.

The message is:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0x28
fault code		= supervisor read data, page not present
instruction pointer	= 0x20:0xffffffff80c7e806
stack pointer		= 0x28:0xfffffe009c0b84c0
frame pointer		= 0x28:0xfffffe009c0b84f0
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process 	= 3505 (VBoxNetAdpCtl)

I've built the kernel module with and without VIMAGE to test, same problem.
