Public bug reported:
Hi,
this bug appeared in Ubuntu 14.04, Ubuntu 12.04 didn't show this behavior.
I've found a possible predecessor in bug #212684.
Switching to a recent mainline kernel didn't fix this issue.
Starting
$ /usr/share/mdadm/checkarray /dev/md3
will repeat this behavior.

Hi Joseph,
unfortunately the kernel you are offering for testing is for the amd64
platform, but I need it for the i386 platform.

Hello Joseph,
the last kernel, you have prepared for testing contains this bug.
I've just noticed that 3.13.0-031300rc3-generic kernel contains the bug

this. I'll have a deeper look inside, hoping to understand why the bug

Hello Joseph,
before issuing an upstream bug report I tried the first stable release
of 3.18 [0] and I wasn't able to reproduce the bug so far. So you may
suspend or keep this bug report on hold. I'd really like to know if
there is some incidence (i.e. a specific commit) for this bug being
fixed
Version 0.9.1 fixes this bug for armhf and aarch6. I'm using Docker on
both platforms and I'm happy to see that the network startup won't get
confused any more by ubuntu-fan (like version 0.9.0 did). This is what I
can confirm.
What I cannot conform is if 0.9.1 has any impact for people who rely
Version 0.9.1 fixes the bug for armhf and aarch64 in the way that I
won't get an error message any more. I don't use a fan configuration so
cannot tell anything about possible side effects for (active) fan users.

I know.
The question is: Should I modify /etc/network/fan if I'm using private
IP addresses outside of 10.254/16, 172.16/12, 192.168/16, e.g. 10/24 ?
