(Building backbone is 10b2.) I switched to an ACSYS 8-port hub and vr0 is at first lossy (20% ping loss to another machine on the LAN), then locks up within 15-30 minutes, logging many three-line sequences: Jul 28 14:40:07 fireball /kernel: vr0: watchdog timeout Jul 28 14:40:07 fireball /kernel: vr0: reset never completed! Jul 28 14:40:07 fireball /kernel: vr0: reset never completed! Putting a second, different model hub between this system and the ACSYS completely clears the problem. A completely different system on the same ACSYS hub has no problem. Ethernet in "autoselect" mode correctly selects 10baseT/UTP. I don't know how to see the half/full duplex setting. ("ifconfig vr0 mediaopt half-duplex" gives "SIOCSIFMEDIA: Device not configured." >How-To-Repeat: Plug into ACSYS Microstack hub. >Fix: Use a different hub type? >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
