I gotta learn some more about kernel hacking someday.. lol I applied both (new) -10 and -20 patches and removed the test. I doubled the debug-messages that get sent to the PC (the UDP traffic) but it froze (the sender) and stopped sending them after 5 minutes. I guess that's because of the crappy TCP/IP stack on the other side (this is a PlayStation2 application i'm developing, and the homebrew PS2 TCP/IP stack doesn't have a good reputation.) I'm back to normal debugging, I'll test it for a couple of hours. So far, no problem.
