Tuning with 'tzap' now randomly fails, as does 'scan'. Of course I cannot rule out that the hardware is starting to wear down, or that there are problems on the transmission side, but these problems started after upgrading my kernel, so I thought I'd ask here. Googeling for any changes, I so far only found this commit that affects the vp7045 driver: http://patchwork.linuxtv.org/patch/258/ (committed as f2685ef0fbc5fff0a8f1cdc204bf37ab0c9a04a7) This is the output I get from 'tzap' when it fails: __ using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' reading channels from file '/home/spock/.tzap/channels.conf' tuning to 618000000 Hz video pid 0x0221, audio pid 0x0222 status 00 | signal 5f00 | snr ffff | ber 00ffffff | unc 0000ffff |=20 status 1f | signal 0000 | snr ffff | ber 00ffffff | unc 0000ffff | FE_HAS_L= OCK status 1f | signal 0000 | snr ffff | ber 00ffffff | unc 0000ffff | FE_HAS_L= OCK [..] __ or sometimes I get this: __ [..] status 00 | signal 3000 | snr a0a0 | ber 00000000 | unc 00000000 |=20 status 00 | signal 3000 | snr 0000 | ber 00000000 | unc 00000000 |=20 status 00 | signal e146 | snr a0a0 | ber 00000000 | unc 00000000 |=20 status 00 | signal f14a | snr 0000 | ber 00000000 | unc 00000000 |=20 status 00 | signal 2154 | snr a0a0 | ber 00000000 | unc 00000000 |=20 status 00 | signal c141 | snr 0000 | ber 00000000 | unc 00000000 |=20 status 00 | signal f14c | snr a0a0 | ber 00000000 | unc 00000000 |=20 status 00 | signal f133 | snr 0000 | ber 00000000 | unc 00000000 |=20 [..] __ This is the output I get from 'scan', when it fails: __ scanning /usr/local/share/dvb/dvb-t/de-Berlin using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 506000000 0 2 9 1 1 2 0 initial transponder 522000000 0 2 9 1 1 2 0 initial transponder 570000000 0 2 9 1 1 3 0 initial transponder 618000000 0 2 9 3 1 2 0 initial transponder 658000000 0 2 9 1 1 2 0 initial transponder 682000000 0 2 9 1 1 2 0 initial transponder 706000000 0 2 9 1 1 2 0 initial transponder 754000000 0 2 9 1 1 2 0 initial transponder 778000000 0 2 9 1 1 2 0 >>> tune to: 506000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_= 16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE WARNING: filter timeout pid 0x0011 WARNING: filter timeout pid 0x0000 ARNING: filter timeout pid 0x0010 >>> tune to: 522000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_= 16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE WARNING: filter timeout pid 0x0011 WARNING: filter timeout pid 0x0000 WARNING: filter timeout pid 0x0010 >>> tune to: 570000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_16:TRANSMISSI= ON_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE WARNING: filter timeout pid 0x0011 WARNING: filter timeout pid 0x0000 WARNING: filter timeout pid 0x0010 [..] __=20=20 (same 3 messages about filter timeout repeating for all transponders) This is the 3.1.1 kernel log when the receiver is plugged in: __ [ 178.480000] usb 1-2: new high speed USB device number 4 using ehci_hcd [ 178.612000] usb 1-2: New USB device found, idVendor=3D13d3, idProduct=3D= 3205 [ 178.612000] usb 1-2: New USB device strings: Mfr=3D0, Product=3D0, Seria= lNumber=3D0 [ 180.588000] IR NEC protocol handler initialized [ 180.624000] IR RC5(x) protocol handler initialized [ 180.680000] IR RC6 protocol handler initialized [ 180.724000] IR JVC protocol handler initialized [ 180.764000] IR Sony protocol handler initialized [ 180.828000] IR MCE Keyboard/mouse protocol handler initialized [ 180.884000] dvb-usb: found a 'Twinhan USB2.0 DVB-T receiver (TwinhanDTV = Alpha/MagicBox II)' in cold state, will try to load a firmware [ 180.904000] lirc_dev: IR Remote Control driver registered, major 251=20 [ 180.904000] IR LIRC bridge handler initialized [ 181.020000] dvb-usb: downloading firmware from file 'dvb-usb-vp7045-01.f= w' [ 181.104000] usbcore: registered new interface driver dvb_usb_vp7045 [ 181.104000] usb 1-2: USB disconnect, device number 4 [ 181.104000] dvb-usb: generic DVB-USB module successfully deinitialized a= nd disconnected.
