TBS-6985 - delivery system 0 is not supported

[andreag0]

Hello,
I am getting often the following error in dmesg:
tbs6985fe - delivery system 0 is not supported
and the vdr stop to work.
I am using the latest driver v151105.
I already di the patch described in this topic:
https://tvheadend.org/boards/5/topics/4355
but I still have the problem.
Someone can suggest me something?
The 6985 is the best one for DVB-S2 or I should upgrade?

Thank you.
