Hi! > i can't initialize my card i have error "unable to determine DMA" > when i > load module dvb-bt8xx I had the same problem. I have mentioned it on the list but never got any answer :( My card was sharing its IRQ with my onboard Ethernet controller. When I plugged my Pinnacle PCTV Sat CI into another PCI slot (IRQ sharing with an onboard USB hub) the error disappeared. Now dvb-bt8xx seems to load correctly but unfortunately I get another error when loading the module dst. Maybe it is still a IRQ problem? Here is the output of dmesg: bttv: driver version 0.9.12 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:02:0b.0, irq: 23, latency: 64, mmio: 0xf7efe000 bttv0: detected: Pinnacle PCTV SAT CI [card=113], PCI subsystem ID is 11bd:0026 bttv0: using: Twinhan DST + clones [card=113,autodetected] bttv0: gpio: en=00000000, out=00000000 in=00fda4fd [init] i2c_adapter i2c-0: Registered as minor 0 i2c_adapter i2c-0: registered as adapter #0 bttv0: using tuner=4 i2c-core: driver i2c TV tuner driver registered. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0060 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0061 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0062 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0063 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0064 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0065 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0066 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0067 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0068 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 0069 i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006a i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006b i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006c i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006d i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006e i2c_adapter i2c-0: master_xfer: with 1 msgs. i2c_adapter i2c-0: found normal i2c_range entry for adapter 0, addr 006f i2c_adapter i2c-0: master_xfer: with 1 msgs. bttv0: add subdevice "dvb0" bt878: AUDIO driver version 0.0.0 loaded bt878: Bt878 AUDIO function found (0). bt878(0): Bt878 (rev 17) at 02:0b.1, irq: 23, latency: 64, memory: 0xf7eff000 i2c-core: driver dvb_bt8xx registered. attach: checking "bt878 #0 [sw]" find by pci: checking "bt878 #0 [sw]" attach: "bt878 #0 [sw]", to card 0 DVB: registering new adapter (DST). dst_attach: check ci bt878 find by dvb adap: checking "DST" i2c_adapter i2c-0: master_xfer: with 1 msgs. write_dst: write_dst error (err == -121, len == 0x08, b0 == 0x00) i2c_adapter i2c-0: master_xfer: with 1 msgs. write_dst: write_dst error (err == -121, len == 0x08, b0 == 0x00) i2c_adapter i2c-0: master_xfer: with 1 msgs. write_dst: write_dst error (err == -121, len == 0x08, b0 == 0x00) i2c_adapter i2c-0: master_xfer: with 1 msgs. write_dst: write_dst error (err == -121, len == 0x08, b0 == 0x00) dst_check_ci: write not successful, maybe no card? Maybe you should try to plug your card into another PCI slot?
