Workaround: add the cx88xx module option i2c_scan=1 Copy the attached file to /etc/modprobe.d/cx88xx.conf
Analysis: Whilst analysing the inter-dependent modules that rely on cx88xx I did some experimentation with controlling the modprobe order using a custom /etc/modprobe.d/cx88xx.conf with various "install..." directives. Using this I was able to successfully initialise the device on several occassions, but never reliably. That lead to examining the i2c related kernel debug messages and that gave me a hunch to try the cx88xx option "i2c_scan" which does an i2c bus scan when the module is inserted, rather than later. The scan is forced immediately after the call to i2c_transfer() in cx88_i2c_init(). This appears to be a viable workaround for now whilst a permanent solution is developed in the kernel code.
