From: Keith Busch [mailto:keith.busch@xxxxxxxxx] > AER error handling walks the PCI topology below a root port, saving pointers of the pci_dev structs affected by the error along the way. Hi Keith, I've been trying to do an ABA test to confirm that your change eliminates the use-after-free issue we've seen. The race seems to be quite elusive, so I can't reliably reproduce it. Your changes have not been forgotten; I have them staged for further testing. Alex
