I'm not sure how you figured out rmmod/insmoding the driver gets you
working, but I don't see any failure messages in the dmesg log you sent,
I just see:

I believe the PCI interrupt for device 7:4.0 disabled is you unloading
the driver again each time, and I don't see any messages at all that
indicate the driver knows anything is wrong.
can you run 'ethtool -t eth0 offline' after rebooting, loading the
module, ifconfig eth0 up, and waiting 4 seconds?
what does ethtool eth0 say after loading the driver (before you ifconfig
up it?) are you sure you're not having some udev problem? Can you send
the console output or attach it to the bug?

This is a PCI only adapter, FYI.

agreed, something doesn't add up here, yet.
