This looks related to the MSI/kobject issues Veaceslav is working on.
See http://lkml.kernel.org/r/1379382464-7920-2-git-send-email-vfalico@redhat.com
and related messages.
We don't have a resolution yet. If you have
CONFIG_DEBUG_KOBJECT_RELEASE=y, you could try turning that off. I
don't know if it would help, and it would only be a temporary
workaround anyway.

I've looked at the original post -
http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg510798.html
hope that's it - and it seems that it's disabling DEBUG_KOBJECT_RELEASE
won't help - the warning is about the re-registering, not about freeing it.
As a workaround I'd suggest adding some kind of delay between removing and
adding the msi - as in - rmmod e1000e; sleep 1; modprobe e1000e; - or
something like that, so that there is enough time for the /msqi_irqs/ to go
away.

I'm not readding e1000e modules myself - however I've no idea what
NetworkManager does. Here are messages prior warning:
NetworkManager[304]: <info> monitoring kernel firmware directory '/lib/firmware'.
NetworkManager[304]: <info> rfkill1: found WiFi radio killswitch (at

So it looks like 'bringing up' causes recreation of msi_irqs ?

Yep, seems like that. .ndo_stop() (e1000_close(), which removes msi irqs
and the /msi_irqs/ kset) instantly followed by .ndo_open() (e1000_open(),
which enables the requested msi irqs via pci_enable_msi() - and,
consequently, re-creates the /msi_irqs/ kset) triggers it - because the
kset, in the meanwhile, isn't freed - maybe because of some readers, maybe
because of the delay introduced by DEBUG_KOBJECT_RELEASE.
I'm now slowly fighting this (and adjacent) issues, will put you on CC if
I'll come up with patches.
In the meanwhile - can you please try disabling DEBUG_KOBJECT_RELEASE and
test if you see the warning _constantly_?
Cause if you do - we might have another issue here...
