Never, ever, ever drop the Cc to the mailing list. By doing that, you are 
requesting private consultation, but without any offer to pay for such personal 
service. That is rude. In fact, I usually ignore such postings.

On the other hand, this description of the problem is nearly perfect. The reader 
does not have to look at pages of information that is likely not significant.

To address your problem, power saving does not work correctly on this device. 
That is why there are numerous posts on the web telling people to use ips=0. It 
seems that Ubuntu people never look at anything but the Ubuntu literature; 
however, I'm sure that I posted this "suggestion" there as well. The Realtek 
group is currently rewriting the entire dynamic management code for all their 
drivers. When complete, this should improve performance and should help the 
power-save condition. No, I do not know when the new code will be ready, or how 
much improvement it will make.
