Perhaps if you can provide patches against the 8.0-REL msk(1) to make it = extremely verbose, I could provide the output and we might learn more = about the cause of this issue. The fact that it's so easily reproduced = must play in favor. I'm afraid I simply have not got the time and resources to learn about = both the FreeBSD kernel + module writing and network interface driver = operations. The only alternative would be to wait until somebody that = does happens upon this hardware.=
