You have 2 Broadcom devices in your system.  07:00.0 is a wireless
device, I think.  8:4.0 is the tg3 device.

It's clear that the tg3 device is still in D3 state after resume and
that explains why all register accesses fail.  tg3_resume() should put
the device back in D0 state in a very straight forward way and I don't
see how that can fail.  It worked for me when I tested it last night.
Can you add some printk() to tg3_resume() to see what's happening?  Let
me know if you want me to send you some debug patches to do that.

Thanks.

Here's the before and after for 8:4.0:
