Either the driver changed, or your hardware. As I've already pointed out, if your BIOS or board arrangement changed, all bets are off. As for the driver code, you have the CVS repo, go look for yourself. (Note: I have a number of systems using these devices, and I can't recall how long it's been since I saw a transmit underrun. It's not an intrinsic feature of the device or driver, it has to be an interaction issue.) -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
