    [PATCH] PCI Hotplug: shpchp: AMD POGO errata fix · 53044f35
    Keck, David authored
    This patch fixes the AMD POGO errata on the hotplug controller where the
    platform will lock up or reboot if PERR/SERR generation is enabled and a
    slot is sent an enable command.  This fix disables PERR/SERR generation
    before a slot is sent the enable command by first saving related
    registers, turning off SERR/PERR generation, enabling the slot, then
    restoring the registers.
