And on the big gotcha's I have found one more I am tracking.

I am seeing pci bridges with a NULL pointer for the subordinate bus.
Earlier I had thought that this was a symptom of the double remove
but I have been able to reproduce it without that.

On just a little bit deeper investigation it looks like the cases
are dying are all coming when the nested bridge reappears.

Which is wrong on so many levels as I am toggle power to the outer
slot, so the nested bridge should not even exist at that time. Ugh.
More tracing to for me on that one.

watch -n1 lspci -t seems like a good way to exacerbate races, when performing
hotplug tests.
