Question about cards

[joolzg]

We have multiple machines (30+) and all use TBS cards BUT we have a problem which I would like to see if other people are having as well as us

1. Cards used are DVB-T/DVB-S/S2

2. Ubuntu 14.04 on all machines

3. We try and update to latest firmware as often as possible but due to not wanting to take machines down some have been runnning 300+ days, these have older firmware.

4. dvblast is being used to stream the data over multicast

Now the problem.

Every now and then a machine loses its input signal and the 9 times out of 10, stopping and restarting dvblast fixes this.

1 out of every 10 times the only fix is a reboot of the machine, again this fixes the problem

Has anyone else seen this, and if so has anyone got a fix

Hi joolzg

Can you tell us that which card you are using for DVB-T/DVB-S.
and for your problem
>Every now and then a machine loses its input signal and the 9 times out of 10, stopping and restarting dvblast fixes this.
This maybe the dvblast issue. which version of dvbalst you are using ?

And please have a try set your PC interrupt to MSI

===
create text file "/etc/modprobe.d/tbs.conf" with line:

options tbs_pcie-dvb tbs_int_type=1
options saa716x_tbs-dvb int_type=1

after reboot, check with "cat /proc/interrupts" that it reports MSI for TBS PCIE.

Thanks

Kind Regards

we have lots and i would have to trawl throught the logs to tell you which machine has which cards.

Lets say we have around 100 cards running and machines at 300+ days uptime, but other machines only work for 10 days and need rebooting to get the signal back

machines that have been reset in the last 7 days have TBS6985 and TBS6820 in them.

Hi joolzg

Do you use TBS6985 and TBS6280 together in one PC or in a seperate PC,all TBS6985 or all TBS6280?

Thanks

after some user feedback with MIS all is ok now you can look here.

So please have a try with MSI.
