I've got a box running FreeBSD 4.2-STABLE (cvsup'd about 2/20). It's
an Intel 815EEA motherboard based on the 815E chipset, with an Intel
82562 integrated Ethernet adapter (on a riser?). The box frequently
gives kernel warnings like:
fxp0: SCB timeout
fxp0: device timeout
corresponding to the box dropping off of the network. Sometimes
permanently, sometimes temporarily. I can't get console access, so I
don't know if "ifconfig fxp0 down; ifconfig fxp0 up" or something like
that helps or not. Anyone seen any similar problems?
I have read the fxp(4) manpage and, as suggested, tried different
cables. The box has also gotten a new motherboard (same model). It's
been connected to different hardware (10Mbps hub and a 10/100 switch).
It did this on 4.2-RELEASE and 4.2-STABLE. Whatever I do, it continues
to exhibit this problem. Go easy here, I don't have physical access,
so there's a bunch of stuff I'd have looked at that I can't verify one
way or the other.
Here's uname -a:
