Ohhh, this is a known bug then. When you kill X while it's not on the

suppose that if you didn't notice it before, it 's because you are
lucky :)

Does it actually hangs ? That's weird... looks like a chip crash. Can
you check if that happens with radeonfb.default_dynclk=-1 on the kernel
command line ?
