Hi Stephen,
Thanks for the advice - I wasn't sure if the list had been abandoned or
someone had been away on holiday ;)
I tried what you suggested and the problem still occurs when taking the
bridge down. Here is the sequence of commands I used to take down the bridge
based on your suggestion:
ifconfig eth0 down
ifconfig eth1 down
brctl delif br0 eth0
brctl delif br0 eth1
ifconfig br0 down
brctl delbr br0
...and again the system hangs with the same unregister_netdevice error :(. I
did try swapping the Realteks for another card, and while I couldn't get
data in/out of the new cards due to driver issues, the kernel correctly
loaded the module and created the ethX and brX interfaces, and again when I
tried to reboot I still got the same error which leads me to believe it's
something in the bridge code.... Any other suggestions???? I've included the
output of "brctl show", "ifconfig" and "route" below (I've obscured the
public facing IPs which is where the bridge operates):
