One of our customers is adamant that linux PCI-E hot-swap support will not allow us to either bring the device up after linux boot (i.e., the PCI-E device must be present when linux scans for PCI-E devices at startup) or to reset the device once linux is up. It was our impression that the PCI-E hot-swap support should allow for devices to appear after linux boot, be properly initialized, and then later be able to shut them down and bring them back up again. Has anyone successfully used the PCI-E hot-swap capabilities in the linux kernel in a PPC 85xx environment? Any known gotchas we need to be aware of? Thanks in advance for your responses, Dan.
