Comment 9 for bug 836062

This problem still exists in Linux 3.13.0-32-generic #56-Ubuntu SMP Mon Jul 7 11:32:12 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

For the record, the symptom that drew me here was the failure to create a /dev/dvb device. I do not know if the IR device was working.

It does appear to be motherboard related. I have two HVR4000s working in another machine. A third one worked in yet another machine. On two identical, but newer motherboards the third one fails intermittently.

For the record, the actual structure of the suggested option file is:
$ cat /etc/modprobe.d/cx88xx.conf
options cx88xx i2c_debug=1
options cx88xx i2c_scan=1

The debug option may be omitted.

Logs can be posted if required, but I suspect a bug with this longevity, affecting obsolete hardware and with only two subscribers is probably best abandoned.
