>Description:
after being able to install NetBSD on our two O2s 10k (thanks to Izumi for the fix!) we now have problems with the network: Both machines constantly throw error messages like

mec0: mec_rxintr: status = 0x8000956ec2ad00a4
Nov 24 18:58:24  /netbsd: mec0: mec_rxintr: status = 0x8000956ec2ad00a4
mec0: mec_rxintr: status = 0x80002edad2ad006d
Nov 24 18:58:25  /netbsd: mec0: mec_rxintr: status = 0x80002edad2ad006d
mec0: mec_rxintr: status = 0x8000318732ad016c
Nov 24 18:58:32  /netbsd: mec0: mec_rxintr: status = 0x8000318732ad016c
mec0: mec_rxintr: status = 0x8000800f4bad006d

Nov 24 18:58:38  /netbsd: mec0: mec_rxintr: status = 0x800047a37bad00a4
mec0: mec_rxintr: status = 0x800088658bad016c
Nov 24 18:58:39  /netbsd: mec0: mec_rxintr: status = 0x800088658bad016c

as soon as network is configured. Needless to say that no data is flowing. Just once I was able to get one or two pings after a reboot before the errors started.
>How-To-Repeat:
install 2.1 on an O2 10k and configure network
