Bug Description

Running Alpha-4 Intrepid with ifenslave package installed. Operating bonding module in mode=4 with miimon=100 with two gigabit ethernet interfaces.

If you enslave eth0 and eth1 to bond0 then the LACP protocol appears to run, but the two interfaces do not aggregate. (One is essentially left in standby).

Yet the process works fine on the same machine running Fedora 9 (2.6.25.14-108)

Fedora 9 is using Bonding Driver v3.2.5 (March 21, 2008).

Intrepid is using v3.3.0 (June 10, 2008)

Hi Neil,

Care to attach your dmesg output when trying the 2.6.27 Intrepid kernel. Just curious what messages (if any) get logged. Thanks.

Now on:

Linux test1 2.6.27-5-server #1 SMP Fri Oct 3 01:16:59 UTC 2008 x86_64 GNU/Linux

so I can use my e1000 again!

It appears that the bonding driver will create an LACP bonding pair on boot up without problem.

However if I do

ifdown bond0
ifup bond0

then the bonding fails to recover.

This is the output from the bond0 description when the bond has been brought back up.

The link is now unusable for TCP. SSH does not work into the server even after restarting the daemon.

You get exactly the same problem if you do

/etc/init.d/networking restart

Hi Neil,

Unfortunately it seems this bug did not get addressed yet. Just to keep the report current, I'm curious if you'd been able to test and confirm this is still an issue with the latest Jaunty 9.04 release? Please let us know your results if you are able to test. Thanks.

I can't I'm afraid. The system has now gone live on Hardy and the kit
has moved on.

Sorry.

Thanks Neil, I'm going to go ahead and close this bug then. Feel free to reopen if the system is ever updated and still experiences this issue. Thanks.
