2.6.30 kernel panic with any network driver

[John Linn]

I just merged in 2.6.30 into our tree and I'm seeing this only when I
have a network driver built into the kernel, and it doesn't seem to
matter which network driver.

 

Maybe I missed something I need to update in our network drivers to
match the kernel.

 

Thanks for any help,

John
