Hello,
I can reproduce a panic by just starting a virtual machine with
VirtualBox 4.2.16_2.
Unfortunately, as the kmod driver is not built with debug symbols I
could not provide much information.
Debug symbols are in option in the port (make config)
It's hard to say without a bt.
Regards
Yes, I finally made DEBUG symbols enabled, there is the panic backtrace:
Unread portion of the kernel message buffer:
