broken fxp driver in 4.x ...

[Colin Farley]

I have made this change on the switch my virtual machines are connected to.
We use HP PorCurve switches, unfortunately the switch needs to be rebooted
for the change to take effect, I will have to do this late tonight.  I will
let you know the outcome.

This only applies if they're using the Spanning Tree Protocol option
(otherwise there's no reason I'm aware of that making a switch change
would cause the problem to disappear, unfortunately).

set spantree portfast M/P enable

where M is the module and P is the port.

The switch will display a significant caution statement when the command
is issued, but it should only apply if you're attaching a switch or some
device that talks to the network like it's a switch (I think we have some
hosts like that, 802.1q aware load balancers).
