}

ok, that explains it!

Hi,

Kevin did this fine job in v1.  Basically it assigns irqs for PCI devices
in case of PIRQ table doesn't work.  I have been using in different
place.  I also think it would be nice to do it in config file instead
of in source just like geode.  Ron, does epia work now?

I'm not getting any ethernet interrupts. The packets get out, they get 
responsded to, but the node never gets the interrupt.

Also, I get these messages after a while:
eth0: Transmit timed out, status 1003, PHY status 786d, resetting...

I assume this means no TX IRQ. Blast. What do I look for?

Can you email me the log.  Since I don't have epia right, reading the log
is the best I can do.

hang on, I won't mail log just yet, I think I may have something.
