   2 Subject: PCI: AMD 813x B2 devices do not need quirk
   3 References: bnc#477675
   4 Patch-mainline: 2.6.30

   6 Turns out that the new AMD 813x devices do not need the
   7 quirk_disable_amd_813x_boot_interrupt quirk to be run on them, if it is,
   8 no interrupts are seen on the PCI-X adapter.
