When I try to start a virtual machine VirtualBox 1.5.2 OSE and the
host kernel is ~hardened-sources-2.6.23, the virtual machine window
freezes and I find the following in dmesg :

I have no problem running Windows and Linux guests inside VirtualBox
on gentoo-sources. UDEREF is not enabled in my kernel config as I read
it does not work with virtualization. I also disabled MPROTECT on the
binary, otherwise PaX simply kills VirtualBox.
