--- NEW FILE linux-2.6-e1000-no-msi-warning.patch ---
commit e94bd23f67c87011f012f26ca0af3fcf6878eeac
Author: Auke Kok <auke-jan.h.kok at intel.com>

    e1000: Fix msi enable leak on error, don't print error message, cleanup
    
    pci_enable_msi failure is a normal event so we should not print any error.
    Going over the code I spotted a missing pci_disable_msi() leak when irq
    allocation fails. The whole code also needed a cleanup, so I combined the
    two different calls to pci_request_irq into a single call making this
    look a lot better. All #ifdef CONFIG_PCI_MSI's have been removed.
    
    Compile tested with both CONFIG_PCI_MSI enabled and disabled.
