Does the likelihood of the failure change when "ips=0" is used?

The Realtek group made several changes in the driver that Chaoming sent you that 
have not yet been incorporated in the kernel version. If you test that driver, 
we might learn if any of them are important to your problem. As neither of us 
can duplicate your results, it is not possible for us to do those tests.

I agree that we want to fix the kernel version. It is unfortunate that Realtek 
does not generate their improvements as patches to that kernel version, and 
publish them that way, but that is a fact of life. When they produce a new 
version, I have to look at the diff file between it and the previous version and 
test those differences with my devices. Thus far, there have been no changes 
that have any effect on my system, but who knows on yours. Please run the test 
as Chaoming asked you to do.

Thanks,

Larry
