gem0 problems with 6.2

[emre n/a]

Hello,

I'm having a lot of difficulty getting networking to work.  I have a  
grey 867Mhz PowerMac G4 (with mirrored drive doors).  It's a vanilla  
install.

In dmesg I get:

[...]
gem0: <Apple GMAC3 Ethernet Adaptor> mem 0xf5200000-0xf53fffff irq 41  
at device 15.0 on pci2
miibus0: <MII bus> on gem0
ukphy0: <Generic IEEE 802.3u media interface on miibus0
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX. 1000baseT,  
1000baseT-FDX, auto
gem0: 10kB RX FIFO, 4kB TX FIFO
gem0: Ethernet address: 00:03:93:bb:ea:de

In rc.conf I have defaultrouter="xxx.xxx.xxx.xxx" and  
ifconfig_gem0="inet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx" set.   
Netstat shows absolutely no traffic, I can't even connect to machines  
on the local subnet.  Our network is setup to give out IPs using  
DHCP, and also automatically assigns a 2001: IPv6 number.  Neither  
happens here.  The network cable is plugged in and I can confirm that  
nothing is wrong with the network (plugging a different machine into  
the same ethernet jack works without any problems -- static, DHCP and  
IPv6 configs all work fine and as planned).

here's the ifconfig gem0 output:

gem0:  flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>  mtu 1500
                 options=9<VLAN_MTU>
                 inet xxx.xxx.xxx.xxx netmask 0ffffff00 broadcast  
xxx.xxx.xxx.255
                 ether 00:003:93:bb:ea:de
                 media:  Ethernet autoselect (none)

with "xxx.xxx.xxx.xxx" being my real IP and netmask respectively.   
netstat -rn also shows me the correct gateway.

I've also tried NetBSD/macppc with these settings and it seems to  
work fine.  I've run out of possible solutions for this.  Does anyone  
know what could be wrong?  I wanted to try out one of the -current  
ISOs, but unfortunately they don't boot (gives me kernel panic in the  
middle of booting sysinst).

Take care
