I disassembled the DSDT from http://bugzilla.kernel.org/show_bug.cgi?id=4773 (I attached the disassembly at http://bugzilla.kernel.org/attachment.cgi?id=15448&action=view), and the _PRT contains "_SB" and "ISA" (no trailing underscores): Package (0x04) { 0x000DFFFF, 0x00, \_SB.PCI0.ISA.LNKA, 0x00 } But by the time we get to acpi_pci_irq_add_entry(), we've added the underscores somewhere (see http://bugzilla.kernel.org/attachment.cgi?id=15423&action=view): 0000:00:0d[A] -> \_SB_.PCI0.ISA_.LNKA I don't know where this happens, but it certainly confused me, and it seems like it could lead to other bugs.
