I have been running the HD3000 drivers on an x86_64 kernel (2.6.17) for several months. I am attempting to resolve a sound driver bug, and so I recently built and installed 2.6.19-rc4. When I attempt to use the drivers shipping in the new kernel, I get this error message repeatedly in my syslog:
or51132: Waiting for firmware upload(dvb-fe-or51132-vsb.fw)...
or51132: i2c_writebytes error (addr 15, err == -121)
or51132: load_firmware error 1
or51132: Writing firmware to device failed!
Is this an HD3000-related bug, or do I need to look elsewhere?
Thanks,
Mike |

| It looks like the nVidia binary driver has something to do with this. The i2c errors only happen when the nvidia kernel module is loaded. Note that I had to remove slave_send=NULL and slave_recv=NULL from the nv_i2c_algo struct in order to get nv/nv-i2c.c to compile against 2.6.19-rc4. This shouldn't impact the driver, so there is probably some i2c breakage due to API changes in the newer kernels. |

The I2C speed for the cx88 driver was increased recently. I'm not sure where it 2.6.19 it went in, so maybe it's not in your kernel. My HD-3000 doesn't seem to like the faster speed and I needed to lower it.
Try setting the i2c_udelay parameter of the cx88xx module to something like 6 or 7. That will slow it back down some. |

Problem still there in 2.6.19 |

| I just tried again (Gentoo, 2.6.19, x86_64, HD3000, nvidia) with the exact same results. Setting the i2c_udelay=6 or i2c_udelay=7 module option for cx88xx has no effect. |
