Hi Paul,

I was tracking down why my XO-1.5's would never dim/blank in the normal
course of operation with version 46. I chose to modify version 44 as I
was working with that as a baseline for some modifications. Well I
turned my attention to version 46 and I think I found the issue I was
having. In r1.patch I added some tracing to laptop_busy to get some idea
what was occurring, it looked like cpu_or_network_busy was keeping the
laptop from suspending, so I added r2.patch to capture more data. The
tracing uncovered on a XO-1.5 that check_network_activity would always
return 0 thus preventing the next step in the cycle from occurring. I
corrected the issue for me with r3-patch. What are your thoughts?

Jerry
