2. I got this inconsistent lock state, i've not seen before:
I know what causes it. It's this change:

net: Fix for initial link state in 2.6.28

It causes us to now call the linkwatch even trigger code inside of
software interrupt context, but that is illegal because that code path
takes the dev_base_lock rwlock as a writer.

I'm going to revert, and Michael will need to find a way to fix the
initial link state issue without adding locking problems :-)

Ok, here's another try. Rather than find a safer way to sync up the
operstate variable with the normal state flags I decided to just nuke
operstate entirely, it just duplicated what was already in the state
flags for the most part.

Hi Michael,

i just compiled my current net-2.6 with your new patch and had no problems booting my machine afterwards.

Holding the relevant information in one place looks like a good approach to me even though i did not test the functionality in detail.

Thanks,
Oliver
