Even more HVR-950q fixes….
Continued debugging has produced another dozen fixes for the HVR-950q. Most of these are low-probability failure conditions (race conditions, etc). However take a bunch of 1/1000 chance items together and you’re likely to hit one of them once in a while…
A couple of noteworthy changes:
- Firmware load time has been sped up to 2.9 seconds (down from 8-10 seconds). This should eliminate the need for MythTV users to specify the “no_poweoff” xc5000 modprobe since it will now load fast enough to avoid a mythfrontend timeout.
- Fix a case where the xc5000 tuner enters a failure state and all subsequent tuning requests fail until the device is reset.
- Minor speedup in switching from analog to digital mode and vice-versa.
The git tree is the same as the previous post – I’ve just added more patches to the end of the series:

Comments/feedback welcome, as always.

I have a comment, more like a question. How can I download these fixes, then integrate that in my current ubuntu distro ? Because I really want my hauppauge 950q to be as good as it could be (windows users beware) especially with the XBMC media center. That xbmc program is so great… I won’t need windows anymore if the xc5000 module driver works all the time.
Hello Joel,
I will hopefully be submitting the patches upstream this weekend. Once they are merged, you can follow the standard “media_build” procedure described on the linuxtv.org wiki in order to update your system.

Devin
I think i got all the bugs you described in your blog… I tried Linux mint 11, 13, Ubuntu 12.04, Peppermint OS, XBMCbuntu, changed the kernel a few times…
The only thing I’ve done that worked was to blacklist the module from loading, then load the xc5000 first, then load the au8522 sound module later …. and then i found another problem and wiped the partition clean to reinstall linux and hit the bugs again.

Hi Devin – I built this tree and was able to boot without getting the ““Device not found†error when not using no_poweroff=1. You mention a fix no longer requiring that option to work around a mythtv timeout, and I assume that may have helped this too. Anyway, seems great so far and I’m really looking forward to updating my system with these fixes full-time – tuning is so much better. Thanks tons!
