I'm testing out this patch on an debian box.
There seems to be a problem with enable_irq in the e100 driver that 
makes the network to b0rk.

What information do you need to get something useful out of this?
I saw that others have this problem, so I've got an serial console to 
the box, if you want me to do any tests, tell me how.


Regards,
Magnus
