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. Eric
