Yes, this is because the module loads, but the driver part of it doesn't
(new driver model, where drivers can be registered without actually
handling any devices, so they can be bound to hotplug devices lateR).


The driver part probably fails to load because it happens to run into
those errors you report during the initialisation fase. Strange though
as during init it retries all things 3 times, which goes to show that
indeed your uGuru is unwilling to talk for a while, as seen before with
early uGurus, what motherboard do you have. Lemme gues one out of this
list? : AI7, KV8-MAX3, AN7
