Hi,

I have some problems in my Linux server for TBS 6908 cards.
Here are my system information.

Code:

root@RF-Parbat-Test:~# uname -a

NUMA node1 CPU(s):     8-15,24-31


Problems:
  1. RF graph (spectrum scan) is not 100% same compare to Windows (CrazyScan) with same signal and same DVB card.
  2. In blind scan, I get plus 1 or 2 MHz freq in almost every transponder with compare to CrazyScan and LyngSat.
  3. I can not find SNR in tbs cards, I got 0 SNR but I can find SNR for Prof 7500
  4. And some time I can not get current constellation picture

1) RF Graph comparison: 
RF-issue.png 

RF graphs are identical to each other, technically its correct but in CrazyScan graph range is big while in here, range is too small.

For example here crazyscan's graph range is ~ -45 to -60 (total range is 15 dBm) but in Linux its ~ -40 to -45 (total range is 5 dBm).



2) Wrong Freq:
in Linux with TBS card:
wrongFreq.JPG 
In LyngSat:
WrongFreq2.JPG 

3) Can't find SNR:
Please check about picture (for wrong freq in Linux), you can see SNR = 0 there.

4) Constellation Picture:
I got wrong freq, its should be 3877 (reference from LyngSat.com) and still I can get TS stream but got bad constellation picture!

Here is original picture:

Thank you [smile]

Doesn't look like anything I have seen.
Are you going to publish your program and the fixes for your TBS 6908 Card?

No I do not have or use your program, nor do I have or use your hardware.basically, thinking you are on your own since you are the only one with your program and your hardware.

They freq difference of a meg or 2 is normal between devices and you may not get the same the next time you scan with the same device and with the SR pretty much the same story.

Quoting Rick at the bottom of this forum's main page:

"Different receivers and LNB's will give you different Frequencies and Symbol Rates."

As far as the other since you refuse to post your code; no one has any clue what you have done and can not make any suggestions so I have to back up what majortom's response was above on the other matters.

Latest kernel update is being pushed upstream note the commit entry

fix merge issues for 4.14-rc2. note the README; you must install libelf-dev PRIOR to compiling and installing this kernel, your system will not boot otherwise. I also had to install the latest ath10k firmware so if you use this wifi device you might want to reinstall the firmware as well

I also had to change apparmour from enforce to complain on cups-browserd and dhclient

Code:
updatelee@updatelee-XPS-13-9360:~/src/UDL/v4l-updatelee$ ls -la /etc/apparmor.d/force-complain/

total 8
drwxr-xr-x 2 root root 4096 Sep 29 13:41 .
drwxr-xr-x 8 root root 4096 Sep 29 13:40 ..
lrwxrwxrwx 1 root root 16 Sep 29 13:41 sbin.dhclient -> ../sbin.dhclient
lrwxrwxrwx 1 root root 24 Sep 29 13:41 usr.sbin.cups-browsed -> ../usr.sbin.cups-browsed
updatelee@updatelee-XPS-13-9360:~/src/UDL/v4l-updatelee$


I would highly recommend always that you compile and install the new kernel and TEST before removing the old one.

Compiled and installed new kernel and tested all my devices (Prof 8000, 955Q and  Geniatech HD Star) and all work good.

Thanks UDL.

wasn't in the cockpit with apparmor (that's the correct spelling[biggrin]), so here is what I had to do so far...

look for any being blocked in dmesg
check and look for their status...

ps auxZ | grep -v '^unconfined'
or
sudo aa-status

I saw /sbin/dhclient and /usr/sbin/cups-browsed, and /usr/sbin/mysqld also.
I didn't have this package installed. So while booted in the previous kernel
apt install apparmor-utils
after installing that, to do what you did...

sudo aa-complain /usr/sbin/cups-browsed
sudo aa-complain /sbin/dhclient
sudo aa-complain /usr/sbin/mysqld
sudo reboot

Then since my isp is finished with their IPV6 conversion around here, by default I am ipv6 all the way. and couldn't
respond to this thread as the forum isn't configured for ipv6 support yet.
http://ipv6-test.com/validate.php then test http://gofastmotorsports.com for example

Until I ran dhclient manually to obtain an ipv4 address from my router on my pc.
sudo dhclient

After a disk crash I've had to start from scratch.                
Previously had updateDVB running on my quad core with a TBS6903 and Nvidia graphics
Installed Ubuntu 16.04 LTS 64bit.
Followed the v4l-updatelee instructions best I could.

Able to boot to  4.14.0-rc5+  But the LAN wont establish a connection.
Going back to 4.10.0-38 generic is fine.

I checked the menuconfig and it looks like the networking is enabled.

What did I miss?

Intel Pro/1000 (e1000e)

did you read Post #1808 and my post just before yours?
try this while booted in the 4.14-rc5 kernel
'sudo dhclient'

should work

Thanks for tip but no joy.
just compared the lsmod | grep e1000e between the two. They look the same.

Been pokin around at this all morning.  It's also the second go at it this week

I have not had any issue here with my distro and do not even have the dhclient command so I am on the outside looking in and some parts do not make any sense to me. But from what I seem to understand try this with your Network Manager and restart the network or reboot.

no joy here darksky.. I think it is a debian / ubuntu issue ever since that kernel version...
with init scripts or sumthing...
here, on the mint 18.x machines, even though once booted up and user logs in,
ifconfig shows a valid ip v4 addr on the network interface (ifconfig), that by all rights should be working...
however, for me, I still have to run 'sudo dhclient' manually again to get the interface to actually function as expected... upon which I get this in response:
RTNETLINK answers: File exists

after which all is well from then on..
every reboot since that kernel it's been necessary for me and I have not tried to chase it down.
The other Mint machine on ethernet behaves the same way as this one which is on wifi ...
I don't know what else to suggest for Warped.

Another thing I notice since that kernel on the Mint machines is that it takes a long time to complete all the init scripts while booting...
A lot of these messages in the console
Starting LSB: some daemon or process .... which seem to hang for a while toward the end.
I may start stripping unused services / programs that I really don't need to see if one stands out as a culprit of hanging...
But I'd have to manually write them down as there isn't really a way to capture a screen shot at that point, other than say with a phone...
I have never noticed any hanging init scripts prior to that kernel on either machine. So somehow I think it is related.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
