Subject: Hauppauge WinTV regreession from 2.6.24 to 2.6.25
Date: Sat, 19 Apr 2008 21:57:39 +0100	[thread overview]
Message-ID: <480A5CC3.6030408@pickworth.me.uk> (raw)

I am testing a kernel upgrade from 2.6.24.to 2.6.25, and the drivers for 
   the Hauppauge WinTV appear to have suffered some regression between 
the two kernel versions.

The problem is that the tuner is not being detected and set correctly 
for either the video or the radio device on the card.

Details are below - the problem appears to be in the detection of the 
tuner type from the tda9887 chip not then being picked up by the tuner 
module. So, in 2.6.24 it successfully gets:

tuner-simple 4-0061: type set to 38 (Philips PAL/SECAM multi (FM1216ME MK3))

but in 2.6.25 it seems to fail:

tuner' 4-0061: tuner type not set

I'm not sure what more information I can provide - if anything will help 
diagnose the problem better please shout. I am just using the stock 
Gentoo kernel by the way - drivers are as they come with the kernel 
release in both cases.

Regards
Ian

For kernel 2.6.25, the system log shows:
