Hi,
I've just tried to run VirtualBox on my FreeBSD 11.1-PRERELEASE and it
crashed my machine with a `panic: page fault' message.
Unread portion of the kernel message buffer:
Fatal trap 12: page fault while in kernel mode
cpuid = 2; apic id = 02
fault virtual address = 0x5a
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff80d6b950
stack pointer = 0x28:0xfffffe011a681430
frame pointer = 0x28:0xfffffe011a6814a0
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 = 1225 (VirtualBox)
trap number = 12
panic: page fault
cpuid = 2
