Hi,
seeing the same (using dhcp for getting an ip address):
backes at eule [backes]: hostid
00000000
backes at eule [backes]: ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:76:C0:40:36
inet addr:192.168.179.182 Bcast:192.168.179.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:284 errors:0 dropped:0 overruns:0 frame:0
TX packets:256 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:86392 (84.3 KiB) TX bytes:25620 (25.0 KiB)
Interrupt:22 Base address:0x2000
Not seeing this effect on systems without dhcp usage.
Regards
