Re: [Em28xx] Cant tune into any channel with kernel 2.6.28

Now it's working :) 2.6.28.1, x86_64 (using ArchLinux)

Thank you!

 Hello Márton,

 It would make sense that the fix you proposed would address the issue.
  It might be worthwhile to consider auditing the other upstream
 drivers that are provided unaltered to see if any other fixes
 improve the general quality for users of the em28xx-new codebase.

 Regards,

 Yes, you are right. These two lines break the channel tuning:

 V4L/DVB (9634): Make sure the i2c gate is open before powering down tuner

 It is not safe to assume that the i2c gate will be open before issuing the
 command to power down the tuner.  In fact, many demods only open the gate
 long enough to issue the tuning command.

 This fix allows power management to work properly for those tuners behind an
 i2c gate (in my case the problem was with the HVR-950Q)

 Hello Márton,
 
 First, some background:  Some hardware designs prevent i2c access to
 the tuner chip unless you explicitly open what's known as an i2c gate.
  The i2c gate is usually in the demodulator, and blocks all i2c
 traffic to the tuner.  This is typically done to improve the tuner
 chip's performance, as the chip does not need to look at the i2c
 traffic.  When you want to send the tuner commands, you open the i2c
 gate, send the command, and then close the gate.
 
 The bug that I fixed was a case where the i2c gate was not being
 opened before the dvb frontend sent a command to power down the tuner
 at idle (a good practice for USB devices to save power when it is not
 in use).
 
 Now, in this case, it is possible that there was some other bug in the
 driver for the tuner chip, but it was not being seen before my fix was
 made because the tuner was not being sent the power down command
 (because the i2c gate blocked the traffic).  It is certainly possible
 that my fix exposed this other bug.
 
 Because you are using an out-of-kernel driver, you will need to take
 this up with the maintainer for the em28xx-new codebase.

Dear Devin,

thank you for your response.

  Hi,
 
  has anyone gotten em28xx to work with kernel 2.6.28 and a Terratec
  Prodigy (DVBT) USB stick?
  With previous kernelversions i had not a single problem, but after the
  switch to 2.6.28 i am getting this if i start kaffeine on the console:

  there is no ca0 in that directory...
  str...@sleipnir ~ ls /dev/dvb/adapter0

  Does anyone know why this is happening?

 Could you please specify which revision of em28xx-new driver
 are you using? You can find it out with hg view command.

 Also, could you please send the output of dmesg?

 Regards,

there seems to be no hg view here on gentoo, but the last changeset 
is: 288:c28b5be6442f.

After modprobe em28xx dmesg says:
