RHEL5 on amd64 processor freeze with virtual Box 2.0

RHEL5 freezes with VBoxManage startvm OSName. Nothing is written in logs, only a hard reset works. Same if guest is started from VirtualBox GUI. The guest OS does not matter since it does not reach the point to start.

Old versions of VirtualBox works just fine. I made a picture to show the OOPS from console screen.
