6.2 SHOWSTOPPER - em completely unusable on 6.2

[glz]

I have seen the watchdog and reset problem on a -STABLE laptop, both em 
and iwi. It only occur when I try to connect using Mulberry e-mail 
client so I thought it could be a problem with the linuxilator.

The load on the box is normally low but both driver have shared 
interrupts, either with cbb or usb. Here is what I can see:

This is a development machine so I can debug and test patches as needed.
