I don't know. Any thoughts from the peanut gallery? I've spent some
time trolling both docs and other drivers, but I haven't yet found an
example of a driver that correctly handles all the resume error cases.
Also, at least one other driver does a pci_disable_device() if the
request_irq() fails - should tulip do this too?
> NAK: What about rtnl_lock()
Gah. Thanks, how about the patch below instead?

From: Francois Romieu <romieu@fr.zoreil.com>
Move tulip_select_media() processing to a workqueue, instead of
delaying in interrupt context, edited by Kyle McMartin to use kevent
thread, instead of creating its own workqueue.
