Description Mostafa Afgani 2008-04-26 12:08:49 EDT
Description of problem:
bttv module needs patching to work with IR receiver bundled with Leadtek WinFast
TV 2000 XP tuners.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Run any recent kernel
Actual results:
IR receiver does not work until patched

Expected results:
IR receiver works "out of the box"

Additional info:
The hardware is fairly old and common. It used to work just fine until the bttv
code "cleanup" sometime last year. From there on, it requires the stock kernel
to be patched before it will work. See:

Comment 3 Chuck Ebbert 2008-05-01 03:15:37 EDT
That patch is in the official 2.6.25 kernel now.
Comment 4 Mostafa Afgani 2008-05-01 05:40:05 EDT
Thanks for the pointer. But from what I can see, the patch is only partial. For
the transmitter bundled with my board,

ir->mask_keycode = 0x8f8;

and not

ir->mask_keycode = 0x1f8; (line 249)

as in the official 2.6.25 kernel.
Comment 5 Bug Zapper 2008-11-26 05:35:01 EST
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '8'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 8's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 8 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
Comment 6 Bug Zapper 2009-01-09 01:26:17 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
