Sorry to bother you guys with that problem. I went ahead and checked
out the version from CVS and it worked a lot better. Sometimes it still
looks like my CPU usage spikes when I am using a lot of bandwidth but
the system never becomes unresponsive like it did before and the
soft_irq error messages are gone from the kernel logs.
I think I read somewhere in a how-to that says if you aren't using your
Prism 2.5 based card as an AP you probably just want to use the orinoco
driver..... that is just plain crazy, this driver works so much better
then that orinoco driver does!
