    SubjectRe: [PATCH] PCI Hotplug fixes for 2.4.20-pre10
    # This is a BitKeeper generated patch for the following project:
    # Project Name: Linux kernel tree
    # This patch format is intended for GNU patch command version 2.5 or higher.
    # This patch includes the following deltas:
    # ChangeSet 1.738 -> 1.739
    # drivers/hotplug/cpqphp_pci.c 1.1 -> 1.2
    #
    # The following is the BitKeeper ChangeSet Log

    # [PATCH] Compaq PCI Hotplug bug fix 2
    #
    # Your patch may fix the issue, but I think there is an
    # easier way. I found another bug that was preventing the
    # existing scheme from working. It looks like the function
    # "pcibios_set_irq_routing" is returning 1 for success, but
    # the hot plug driver was interpreting it as failure.
    #
    # The attached 2 line patch fixes it for me. I am able to
    # add an Intel NIC on an ML370 G2 and receive interrupts from
    # it.
