This is a fix for commit 7897e602 ("PCI: Disable Bus Master unconditionally in pci_device_shutdown()"). Vivek reported that with this commit, kexec failed because none of his SATA disks came up. A ->shutdown() callback might put the device in D3cold, which means config space is no longer available. [bhelgaas: changelog] Link: https://lkml.org/lkml/2013/3/12/529Reported-and-Tested-by:
