>Description:
i have odroid h2+ [1] with the 'net card' [2]. it has two
onboard rge(4) nics and four more on the net card.
using only rge0/1, the system seems stable. but when i try to
bring up more nics, e.g. ifconfig rge2/3/4/5 up, the system will hang. i
cannot do anything, except pressing ^C on the console prints a ^C back
very slowly but doesn't do anything else. it seems like ifconfig is
stuck in kernel, and the system also stops doing anything else like
routing the other working nics.
current setup is rge0 for WAN with dhcpcd from ports for IPv6
access, and bridge(4) + vether(4) + rge1/2/3/4/5 with dhcpd/rad for LAN.
for full config, you can find the ansible scrips at
https://github.com/mischief/ansible/. have never used ansible before so
i am sure it is crappy :)
questions:
1. how can i debug what is happening when i up the nic
with ifconfig?
2. would someone on openbsd team (maybe kevin lo) like a copy of
this hardware donated?
thanks
