>Description:
Ethernet was working for months on a 10b2-to-10bT media converter.
(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?
