Ok, I guess that you only pasted the first lines. What is a little
confusing is your high load. Not only do wineserver and Heavy Weather
eat up all of the CPU, there also are some 20 other apps competing for
it. Either the first two are hogging the CPU so much that everything else
has to wait, or wine spawned a lot of children; my guess is on the first
option.
What is the output of 'setserial -a /dev/ttyS0'?

Not surprising given the above top listing.
