I have an Amptron motherboard with a LinkSys NC100 NIC. Another machine backs the Amptron up by doing ssh dump. This often generates TX underruns for the NIC and the disk read error. However, if I boot the machine up, and directly start this backup, the Amptron hangs consistently, with no error messages. All processes appear to stop and the keyboard is mostly dead -- pressing a function key to switch virtual consoles makes the cursor disappear; pressing a key to switch to an unused virtual console causes an indefinite beep; no other key has any effect. But, sometimes I've seen different behavior than that, e.g., during earlier testing, I was doing the backup after being up longer and while I was doing other things; then I'd see short system freezes (up to a minutish). In some cases, I was able to switch virtual consoles a few times before the total freeze. Setting hw.atamodes=pio,pio, makes everything work. Also, if I replace the NIC with a random ISA part, the problem goes away. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
