I am using Asrock H110 Pro BTC+ motherboard with CPU intel i7 4ghz + 16gb ram ddr4 on this machine..

looks like the kernel is having some trouble in running this multiple cards??????

Our project main goal is to add another 7 TBS6909 cards need to get more 56 Tps up and running soon.. any ideas on what could be the problem?

i have increased the card limit to

Code: Select All Code
sed -i.bak -e 's/^\(CONFIG_DVB_MAX_ADAPTERS\)=.*/\1=48/g' /lib/modules/$(uname -r)/build/.config



and also tried tunning the CPU optimization to
Code: Select All Code
UDP capture setupAnchor
For capturing data via UDP under Linux, the amount of memory allocated to UDP buffers should be increased:

sysctl -w net.core.rmem_max=1048576
sysctl -w net.core.rmem_default=1048576
sysctl -w net.ipv4.udp_mem="8388608 12582912 16777216"
Note that these settings will persist only until reload. In order to save them permanently, edit the file /etc/sysctl.conf by adding at the end of it the following:

net.core.rmem_max = 1048576
net.core.rmem_default=1048576
net.ipv4.udp_mem = 8388608 12582912 16777216
and then running the sudo sysctl -p command to apply the changes.
Working with a large amount of memory Anchor
When more than 60GB of memory is available, we recommend allocating 10GB to the system:

sysctl vm.min_free_kbytes=10240000

Hi Steven

i am using linux source latest github updated driver, aparently this is only happening on 1 card tbs6909 (this card i have full 8TPs running all on Vertical position)

the other 2 cards are running different satelites, 1 card only using 3TPs this is working ok no tp down.. and another card only another 2 tps at the moment.. problem happens only on full 8tp card running .

i will try to make more log message but basically this is the error showing after of couple of hours running..

i am streaming free C band FTA channels so most of them is 1 or 2 channels per TP

13:22:03 MIDDLEWARE kernel:
[47716.274518] TBSECP3 driver 0000:05:00.0: i2c xfer timeout
Jun 1 13:22:03 MIDDLEWARE kernel:
[47716.276392] i2c write error



this error is shutting down the TPs streaming on the card also.. eventually untill full card stops working..

all 3 TBS6909 cards are powered up on the 1000w 80plus gold PSU using the 5 pin adapter.. the only one not connected is tbs6814 because it does not have 5 pin connector.
