>Description:
Hardware is an SMC 9332 EtherPower PCI controller plugged into an
ASUS P/I-P55TP4XEG motherboard. The other end of the UTP cable is a
port on a GVC 24-port 10baseT repeater hub. Approximately 1 out of 3
boots will result in the device probe enabling the 100baseTX UTP port
rather than the 10baseT one (same physical port, different speeds).
The collision and link LEDs for that port on the 10baseT hub are both
on solid when this happens. Normally, only the link LED is lit.
Rebooting the system will eventually fix the problem. The
corresponding driver in NetBSD 1.1 for Intel exhibits the same
problem.
>How-To-Repeat:
Plug the SMC 9332 Ethernet controller into a 10baseT hub and
reboot with the de0 driver.
>Fix:
None known.
