I've looked at the original post -
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
