There are a number of these reports. It appears that with different
hardware there are different results and I have yet to find any pattern to
it. All I've been able to do is for people that have problems, recommend
that they turn the support off and the problem usually goes away.

I myself would recommend this as well. A note that on some systems this
causes problems and to disable this support if you see anything strange
would be wise I think.
