UDEREF

Is it expected Virtualbox 4.1.18 will work Gentoo host kernel 3.4.4-hardened-r3 with UDEREF enabled?
It is crashing for me, but It worked with kernel 3.4.4-r2 without UDEREF.

virtualbox as it exists today is not compatible with either UDEREF or KERNEXEC.

It is expected qemu-kvm will run with UDEREF and KERNEXEC?
It hangs for me with 100% CPU usage.

yes, it's a known problem but unfortunately i don't have enough time/motivation to track down the root cause.
