I've been having recent troubles with an AverMedia 771-T. The problem started after upgrading from Myth 0.16 to Myth 0.17, using the kernel 2.6.6 for both. I have since tried upgrading the kernel to 2.6.11-rc4 but with no improvement. Downgrading to Myth 0.16 isn't desirable. The fault is the occasional lockup of the card with this error in the logs... 2005-03-02 11:25:23.568 DVB#0 WARNING - No data from card in 1 second. 2005-03-02 11:25:24.572 DVB#0 WARNING - No data from card in 1 second. 2005-03-02 11:25:25.577 DVB#0 WARNING - No data from card in 1 second. 2005-03-02 11:25:26.582 DVB#0 WARNING - No data from card in 1 second. This happens during a recording, not during initial tuning. It is also sometimes accompanied by these dmesgs. bt878(0): irq FBUS risc_pc=17d9f010 But I've seen the "No data from card" without those dmesgs, so it might not be related. Sometimes I see this message immediately preceding... DVB#0 WARNING - Transport Stream Continuity Error. PID = 512 DVB#0 PID 512 _continuity_count 12 cc 3 DVB#0 WARNING - Transport Stream Continuity Error. PID = 660 DVB#0 PID 660 _continuity_count 12 cc 13 DVB#0 WARNING - Transport Stream Continuity Error. PID = 650 DVB#0 PID 650 _continuity_count 7 cc 14 Unloading and reloading the frontend (mt352) seems to fix the fault but understandably this is a pain. The signal is admittedly a bit weak, but I do get lock, though note the oddity with "SBS DIGITAL 1". root@stoli:~/.tzap# tzap "7 Digital 1" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 177500000 Hz video pid 0x0301, audio pid 0x0302 status 00 | signal 0e83 | snr 0000 | ber 00000000 | unc 00000000 | status 1f | signal 0e83 | snr d0d0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0e83 | snr d2d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0e83 | snr d2d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK root@stoli:~/.tzap# tzap "SBS DIGITAL 1" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 536500000 Hz video pid 0x00a1, audio pid 0x0051 status 1f | signal 0e83 | snr d2d2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 01 | signal 0e83 | snr 0000 | ber 00000000 | unc 00000000 | status 01 | signal 0e83 | snr 0000 | ber 00000000 | unc 00000000 | status 01 | signal 0e83 | snr 0000 | ber 00000000 | unc 00000000 | root@stoli:~/.tzap# tzap "TEN Digital" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 219500000 Hz video pid 0x0200, audio pid 0x028a status 00 | signal 0dc3 | snr 0000 | ber 00000000 | unc 00000000 | status 1f | signal 0dc3 | snr cece | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0dc3 | snr d1d1 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0dc3 | snr cece | ber 00000000 | unc 00000000 | FE_HAS_LOCK Is it possible that the lockups are simply the result of a weak signal?
