    > Subject: [patch 02/45] IB/mthca: restore missing PCI registers after reset
    > ------------------
    > mthca does not restore the following PCI-X/PCI Express registers after reset:
    > PCI-X device: PCI-X command register
    > PCI-X bridge: upstream and downstream split transaction registers
    > PCI Express : PCI Express device control and link control registers
    > This causes instability and/or bad performance on systems where one of
    > these registers is set to a non-default value by BIOS.

    By the way, Greg, this code is completely generic, and the same seems to apply
    to all PCI-X/PCI-Express devices - should not pci_restore_state and
    friends really know about these registers, as well?

    What do you think?
