| |
I recently ran into a problem where lspci was trying to read pci config space of a pci adapter while the device driver for that adapter was running BIST on it. On ppc64, this resulted in a PCI error and puts the slot into an error state making it unusable for the remainder of that system boot. Should there be some blocking in place so that userspace pci config reads will not occur in these windows or is using tools like lspci user beware? Part of my problem was that lspci was being called as a result of a boot script so on a particular machine I was hitting this every boot.
