I can't reproduce the xterm example on BEST's machines (running 2.2.6). It's definitely reproduceable on my machine (3.0-current). I would like to track down what is causing the problem, so if anyone has any suggestions on where the cpl can be checked for illegal values, I'd appreciate it. I'll retest the VM86 removal to make sure that didn't fix the problem and I'll test the AUTOEOI configs as well. As far as I can tell, the only two places where the bug can possibly be are in the interface driver (pci/if_de.c) or the UDP/IP stack. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
