Sorry for the delay in response. I have been running some more
experiments with this issue to try to gather as much information as
possible. While running those experiments I noticed some strange
behavior on my system with PCI. I finally narrowed down the issue to
an improper power on sequence. After I fixed this, all my issues with
the tg3 are gone (tested with this patch applied). I think we're all
good now.

I'll let you know if I see any issues in the future.

Thanks
