Using Debian with 2.6.20-7 custom kernel and IVTV 0.10.5 with ivtv-fb and Xdriver for my PVR-350 which is used for a combined mythtv 0.20.2 frontend / backend system. I'm getting odd messages shortly after startup and ivtv / ivtv-fb initialization that look like this:
--snip-- msp3400 1-0040: I/O error #0 (read 0x10/0x200) msp3400 1-0040: I/O error #1 (read 0x10/0x200) msp3400 1-0040: I/O error #2 (read 0x10/0x200) msp3400 1-0040: giving up, resetting chip.

Sound will go off, sorry folks :-| msp3400 1-0040: chip reset failed --snip-- The msp3400 I/O warnings go on indefinitely. Although this does seem to hang my mythfrontend (with no apparent error messages in its logs), my myth backed runs fine and captures video and audio with no issues. I've resisted cross-posting this to mythtv-users since at this point it does seem pretty msp3400 specific. But I have a nagging feeling that all is not right with ivtv on my system. I'm hoping some of the IVTV pros can help set me down the right debug path. Any ideas? For the record, here's what dmesg reports for IVTV : ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.10.5 (tagged release) loading ivtv: Linux version: 2.6.20.7 mod_unload CYRIXIII ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist. ivtv0: Autodetected Hauppauge card (cx23415 based) ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 11 PCI: setting IRQ 11 as level-triggered ACPI: PCI Interrupt 0000:00:14.0[A] -> Link [LNKB] -> GSI 11 (level, low) -> IRQ 11 ivtv0: Unreasonably low latency timer, setting to 64 (was 32) pci_hotplug: PCI Hot Plug PCI Core version: 0.5 Linux agpgart interface v0.101 (c) Dave Jones parport_pc: VIA 686A/8231 detected parport_pc: probing current configuration parport_pc: Current parallel port base: 0x378 parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP] parport_pc: VIA parallel port: io=0x378, irq=7 Real Time Clock Driver v1.12ac ivtv0: loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv0: loaded v4l-cx2341x-dec.fw firmware (262144 bytes) ivtv0: Encoder revision: 0x02060039 ivtv0: Decoder revision: 0x02020023 tveeprom 1-0050: Hauppauge model 48132, rev K268, serial# 9945480 tveeprom 1-0050: tuner model is LG TAPE H001F MK3 (idx 68, type 47) tveeprom 1-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 1-0050: audio processor is MSP4448 (idx 27) tveeprom 1-0050: decoder processor is SAA7115 (idx 19) tveeprom 1-0050: has radio, has IR receiver, has no IR transmitter ivtv0: Autodetected Hauppauge WinTV PVR-350 tuner 1-0043: chip found @ 0x86 (ivtv i2c driver #0) tda9887 1-0043: tda988[5/6/7] found @ 0x43 (tuner) tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #0) saa7115 1-0021: saa7115 found (1f7115d0e100000) @ 0x42 (ivtv i2c driver #0) saa7127 1-0044: saa7129 found @ 0x88 (ivtv i2c driver #0) msp3400 1-0040: MSP4448G-A2 found @ 0x80 (ivtv i2c driver #0) msp3400 1-0040: MSP4448G-A2 supports radio, mode is autodetect and autoselect ivtv0: Registered device video0 for encoder MPEG (4 MB) ivtv0: Registered device video32 for encoder YUV (2 MB) ivtv0: Registered device vbi0 for encoder VBI (1 MB) ivtv0: Registered device video24 for encoder PCM audio (1 MB) ivtv0: Registered device radio0 for encoder radio ivtv0: Registered device video16 for decoder MPEG (1 MB) ivtv0: Registered device vbi8 for decoder VBI (1 MB) ivtv0: Registered device vbi16 for decoder VOUT ivtv0: Registered device video48 for decoder YUV (1 MB) ivtv0: loaded v4l-cx2341x-init.mpg firmware (155648 bytes) tuner 1-0061: type set to 47 (LG NTSC (TAPE series)) ivtv0: Initialized Hauppauge WinTV PVR-350, card #0 ivtv: ==================== END INIT IVTV ====================
