Enabling VT-x in BIOS results in instability when using VirtualBox

After turning on virtualization features in BIOS and running VirtualBox version 3.1.4r57640, I experience host OS freezing and host BSOD's (KMODE_EXCEPTION_NOT_HANDLED - usbehci.sys). The guest OS (Windows XP 32-bit) does NOT need to have VT-x enabled for this to happen - enabling it in BIOS setup is enough. The host operating system is Windows 7 64-bit.
