Please let me know what other output besides lspci might be useful. I could still use some help understanding what exactly isn't supported hardware-wise in terms of hot swap for that system. I've included the lspci output for the problematic system above (hostname: fs-2). Update: In perhaps a dozen cases, we've been forced to reboot servers because hot swap hasn't "just worked." Thanks for the answers to look more into the SATA controller.
