gem0 problems with 6.2

Wed Jul 4 02:40:16 UTC 2007

Hello,

Thanks for the quick reply.  I'm not sure what I did, but networking  
is somewhat working, not smoothly however.

I unplugged the cable, plugged it back in, and then  manually ran  
dhclient gem0 after reboot (after an unsuccessful configuration).  I  
got an IP address back and  IPv6 configured itself fine as well.

I put ifconfig_gem0="DHCP" instead of the static IP address into  
rc.conf.  Then I rebooted.  dhclient tries to get an IP address at  
boot-up but fails to get any offers, and ultimately gives up.  It  
then uses the 'recorded lease' IP address, and then everything  
works....sometimes.  It's very random and rarely works.

I changed my rc.conf back to what it was (static IP config), and  
added 'media 100baseTX' at the end.  It seems that it might've fixed  
the problem.  I have no problem getting networking to work now,  
however DHCP still remains problematic.  Maybe it wasn't unable to  
correctly determine the media type?  See dmesg below.

Take care
