I followed the instructions in the Minix wiki on how to set up Minix in VirtualBox, but right after hitting enter on the boot screen, I get a kernel panic:*** kernel messages:ested 0...kernel panic: cause_sig: sig manager 2 gets lethal signal 11 for itself...I'm using VirtualBox 4.1.2 on Ubuntu 11.10. Am I doing anything wrong? How do I convince Minix to boot?
Minix: Kernel Panic when booting from the Live CD

If your hardware supports virtualization, make sure it's activated in the BIOS (some computers have the feature but ship with it disabled). Then make sure that Enable VT-x/AMD-V is checked in the System  Acceleration tab of the VM settings.If that's not a solution for you, from VirtualBox 4.0, instead of booting Minix by hitting the Start button in VirtualBox, use this command to start the VM:VBoxSDL --startvm Minix 3 --norawr0 --norawr3(where Minix 3 is the name of the virtual machine)The option --norawr0, possibly combined with --norawr3, can help with other guest operating systems such as OpenBSD, NetBSD, QNX
