What do you mean by "mouse only working" ?
Can you still move the mouse over the screen ?
Can you still click ?
When the system is "freezed", please try ALT+F1 to see if you can switch to the text console.
I see some random problems with alpha6 where mouse clicks just stop to work, the after 1-2 minutes they work again.
Sometimes after switching ALT+F1 and back to X screen.
