I added some printk() to dump the arguments to pci_write_config_*( ) and these are the results for sis3315 in 3.16 which works (values printed are dev, where and val): Aug 7 23:00:47 debian2 kernel: [ 1.709953] PCI W byte: c68ed000 where 0xd = 0x10 Aug 7 23:00:47 debian2 kernel: [ 1.709971] PCI W byte: c68ed000 where 0x52 = 0x4<6>[ 1.709984] sis5513 0000:00:00.1: not 100% native mode: will probe irqs later Aug 7 23:00:47 debian2 kernel: [ 1.710077] Probing IDE interface ide0...
