I have an HVR-950Q: [44847.234403] tveeprom 0-0050: Hauppauge model 72001, rev B3F0, serial# ******* [44847.294643] tveeprom 0-0050: MAC address is **:**:**:**:**:** [44847.343417] tveeprom 0-0050: tuner model is Xceive XC5000 (idx 150, type 76) [44847.402873] tveeprom 0-0050: TV standards NTSC(M) ATSC/DVB Digital (eeprom 0x88) [44847.465471] tveeprom 0-0050: audio processor is AU8522 (idx 44) [44847.515481] tveeprom 0-0050: decoder processor is AU8522 (idx 42) [44847.567162] tveeprom 0-0050: has no radio, has IR receiver, has no IR transmitter [44847.630272] hauppauge_eeprom: hauppauge eeprom: model=72001 I cannot seem to get it to work after removing the au0828 xc5000 au8522 modules and then modprobing the au0828 module. If I physically remove the device and plug it back in, it will work fine, however using rmmod/modprobe it seems to fail on trying to read from it. For example: $ gnutv -adapter 0 -out stdout -channels chans 100-3 just yields a: Using frontend "Auvitek AU8522 QAM/8VSB Frontend", type ATSC status | signal 0000 | snr 0000 | ber 00000000 | unc 00000000 | where the value to the right of the signal and snr toggles between 0000 and 0118 but no output is ever emitted. For what it's worth, the only reason I want to rmmod;modprobe this driver is due to bug #43145. I'm not sure what more information to provide about this but I am happy to gather and provide whatever information you might want. modinfo says au0828 is version 0.0.2 if that is at all meaningful.
Confirmed that the HVR-950q is randomly unable to initialize on recent kernels (since around 2.6.33). Sometimes it will initialize correctly, sometimes it won't. It sometimes gets "stuck" in an unitialized state and won't re-initialize after reinserting or rebooting no matter how many times you try. After some days, it will initialize correctly again. I've most recently tested with linux-3.4.1-rc1.

Is there any testing that I could do to help find the cause of this bug? It's rather frustrating to have a device that works intermittently like this - some days it seems fine, other times no amount of rmmod'ing and replugging has any effect. Just consistent 'device not found at addr 0x61' errors in the log.
