Comment 3 for bug 160006

my system is doing the same thing ie: puts the hd to sleep then tried to write to it and the whole system locks up.
also when it locks up my usb track ball mouse's light goes out

in my logs I'll see bad page or swap space went negitive around the time of the crash.

 I have reported this bug which I think is a Kernel issue with VIA based motherboard ( AMD64 2800+ ) built in video card + having a add in video card ( NV GF6200se)
it never crashed when I was using just the built in video card or at least i don't remember it doing that
