I have a problem where an ich6 (SATA+PATA) is getting its port0 reserved by the pci quirk for libata so that it gets picked up by ata_piix. In current git, ata_piix complains: [ 124.507570] PCI: Unable to reserve I/O region #1:[EMAIL PROTECTED] for device 0000:00:1f.2 I bisected to the same commit, 368c73d4f689dae0807d0a2aa74c61fd2b9b075f, however, your patch doesn't fix my problem. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
