1. OpenBSD 2.9: can't see network until I unplug/re-plug the network cable
I just upgraded a few machines to OpenBSD 2.9 (from OpenBSD 2.7). Now, on
my old Pentium, it can't see the network until I unplug/wait a few
seconds/re-plug the network cable. It's a generic 10/100 card (info from
dmesg below). It was working fine in OpenBSD 2.7... doh.
When I say "can't see the network", everything seems ok from ifconfig etc,
but I can't talk to anything on my local LAN, and nothing on the LAN can
talk to me. When I unplug the cable, wait, and re-plug it in, everything
sees everything. So I'm guessing that something with the media autoselect
might be funky? I've attached my hostname.dc0, maybe it's bad? Since this
was an upgrade, this is left over from OpenBSD 2.7, did something change
When I do a ping from my old Pentium before unplugging, I can see the light
on my hub blinking, so I know it's doing something... maybe it's ignoring
the incoming responses? Got me...
