I must have missed earlier posts in this thread. (Not a surprise, I 
usually only have time to skip over -current.) The problem you are 
describing here is nearly identical to pcm-as-module here, with a 
generic/unknown PHY. I haven't had time to properly debug, since the pcn 
on the system in question is a) onboard and b) the only working NIC with 
driver currently in the system. The symptoms I saw were specifically 
that if pcn was compiled as module and loaded, it seemed not to attach 
PHY properly. Can you try compiling pcn as a module, and seeing if the 
behavior is identical on load? Then try unloading and reloading the driver?
