DViCo Dual Fusion Express (cx23885) remote control issue

Hi,
I recently upgraded my Myth box from Ubuntu 8.04 to 9.10 (runs 
2.6.31-20-generic). Previously I used the drivers from 
http://www.itee.uq.edu.au/~chrisp/Linux-DVB/DVICO/ however the card 
worked out of the box (once I got the later firmware) and so I presumed 
they had been merged.

However one thing that wasn't working was the IR receiver so I checked 
out the latest v4l-dvb code and built it (after disabling the 1394 
based ones as they broke the build) and then installed and rebooted and it
detected the IR OK, ie

Apr 13 14:40:05 mythtv kernel: [    7.601716] input: i2c IR (FusionHDTV) as /devices/virtual/input/input6
Apr 13 14:40:05 mythtv kernel: [    7.632093] ir-kbd-i2c: i2c IR (FusionHDTV) detected at i2c-0/0-006b/ir0 [cx23885[0]]

And it works with lirc etc etc..

However I came to use it this morning and it now doesn't find it even if
I load the module from where it was built..
[mythtv 15:13] ~/v4l-dvb >sudo rmmod ir_kbd_i2c
[mythtv 15:13] ~/v4l-dvb >lsmod |grep ir_kbd_i2c
[mythtv 15:13] ~/v4l-dvb >sudo insmod /home/myth/v4l-dvb/v4l/ir-kbd-i2c.ko

I haven't delved much further yet (planning to printf my way through
the probe routines) as I am a Linux kernel noob (plenty of FreeBSD
experience though!).

If any one has any suggestions or patches I'd be happy to try them
out :)

Thanks.

I found that it is intermittent with no pattern I can determine.

When it doesn't work the probe routine is not called, but I am not sure 
how i2c_register_driver decides to call the probe routine.

Does anyone have an idea what the cause could be? Or at least somewhere 
to start looking :)

Thanks.

A patch was posted that was suposed to be merged that fixed the ir 
problem, at least for me. Though my problem was not intermittent. The 
patch worked for me. Now if I could just get both tuners to keep working

Hmm do you have a subject line or message ID I can search for?

I haven't found any problems with tuners not working although I don't 
often fire them both up at once.

I finally found some time to look at this and found..
https://patchwork.kernel.org/patch/86939/

However I don't see anything in /sys/bus/i2c/devices so I presume it's another issue :(
