You need to track this call. My guess is that it calls into the 82559
driver, maybe i82559_start or i82559_init. You need to see what its
trying to do when it hangs and then work out what the 82558 does
differently than the 82559. At a guess its interrupt handling. Redboot
does polled IO, where as the 'real' driver is interrupt driver.
