Dear List,
i am not so familiar with the deep art of
network internals more with the basics one.
Therefore i have a problem to interpret this
error message:
Dead loop on virtual device br0, fix it urgently!
In the corresponding kernel code i found this quote:
/* It may be transient configuration error,
when hard_start_xmit() recurses. We detect
it by checking xmit owner and drop the
packet when deadloop is detected.
*/
but i still have no idea what could be wrong.
My setup is an bridge (two interfaces) and local
interface. The bridge connects the dmz with the internet.
How can i reproduce this error message - to find the cause.
What does it mean (for a not so advanced admin;).
Thanks in advance for any help.

What kernel version? What are the commands being used to put the devices into the bridge. It looks like a bridge ended up including itself some how.> > My setup is an bridge (two interfaces) and local > interface.
