The following patch removes the device ID 0x9511 from Oxford Semiconductors from this driver. This device is a local bus bridge and not a serial device: 01:05.1 Bridge: Oxford Semiconductor Ltd OX16PCI954 (Quad 16950 UART) function 1 (8bit bus) (rev 01) 01:05.1 0680: 1415:9511 (rev 01) Subsystem: 1415:0000 So there is no need to try to use the bridge as UARTs. :-) Signed-off-by: Rainer Koenig <Rainer.Koenig@xxxxxxxxxxxxxx> --- --- linux-2.6/drivers/serial/8250_pci.c 2010-08-11 09:58:02.000000000 +0200 +++ patch/drivers/serial/8250_pci.c 2010-09-07 08:13:18.000000000 +0200 @@ -3205,9 +3205,6 @@ PCI_SUBVENDOR_ID_COMPUTONE, PCI_SUBDEVICE_ID_COMPUTONE_PG6, 0, 0, pbn_computone_6 }, - { PCI_VENDOR_ID_OXSEMI, PCI_DEVICE_ID_OXSEMI_16PCI95N, - PCI_ANY_ID, PCI_ANY_ID, 0, 0, - pbn_oxsemi }, { PCI_VENDOR_ID_TIMEDIA, PCI_DEVICE_ID_TIMEDIA_1889, PCI_VENDOR_ID_TIMEDIA, PCI_ANY_ID, 0, 0, pbn_b0_bt_1_921600 }, -- Dipl.-Inf.
