Subject:   VirtualBox: reproductible panic

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.

Is this problem already reported?

Fatal trap 9: general protection fault while in kernel mode
cpuid = 1; apic id = 01
