@bigeasy: You have some experience cleaning up this class of problems. Any suggestions?
I though that we have netconsole disabled on RT. As far as I remember it disables interrupts and expects that the NAPI callback (as in interrupts) will not fire not will there be any packets sent. So this is not going to work. It needs to be checked what kind of synchronisation is expected of netconsole by disabling interrupts and providing this by other means.
