Aaron, thank you for your comment. As this bug report is marked Status Fix
Released, it is considered closed. So your hardware and problem may be tracked,
could you please file a new report with Ubuntu by executing the following in a
terminal while booted into the default Ubuntu kernel (not a

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
This seems to have been fixed upstream. Precise doesn't suffer from the
issue - although the HVR-4000 has been moved to a different motherboard.

TJ, this bug was reported a while ago and there hasn't been any activity
in it recently. We were wondering if this is still an issue? If so,
could you please test for this with the latest development release of
Ubuntu? ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .
If it

Update:
Using debugging kernel 3.1.0-rc3+ (commit 7a54f5e19f + debug patches).
dmesg:
cx88[0]: i2c register ok
cx88[0]: i2c init: enabling analog demod on HVR1300/3000/4000 tuner
cx88[0]: i2c init: failed, error=-6
That error is:
#define ENXIO6 /* No such device or address */
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

The first one fixed IR for me some time ago. This line was actual the
fix (for me), the rest are cleanups only:

Does this problem occur 100% of the time at device boot? Or is it an
intermittent issue?
Also, are you sure this happens with the 1300, 3000, and 4000? I'm
asking because I don't think the 1300's IR receiver is supported at all
(it's a zilog as opposed to GPIO based IR).
If this does indeed
Devin: On earlier kernels the tveeprom only seemed to fail on warm
reboots. However, since about 2.6.35-ish it's almost always failed -
although there has been the odd cold or warm reboot that has seen it
working.
It's been on my list of kernel bugs to fix for some time but I've only
