Fedora 14 randomly freeze after installed guest additions

[jzu]

Please help,

Hi all, i got a very strange program with the Guest system - Fedora 14

Inside the X, It was fine, running very smooth before installing the guest additions.
After installed the guest additions, the system will freeze randomly.
Also, the system also freeze (stucked at the wallpaper only screen) on each time if using "log out" or "shutdown". (normally the screen will turn black and continue the operation).

CPU: i3 530
Virtualbox version: 3.2.12 (latest)
IO APIC enabled
processors: 2
PAE/NX not enabled
vt-x enabled


Anyone know what's wrong? Is any setting I should set after installing the guest additions??
Sorry for my poor English grammer.

Thanks

Edit /boot/grub/menu.lst and add 'clocksource=jiffies' to the kernel line.
