Hi,
I continued with investigation. I build new computer, there is only
VDR and two TBS6285 cards.
When I start VDR with one adapter CPU load rises to 2 and after 5
minutes drops to 0.03 . There is no streaming, no playing.
In the syslog are not any bad messages. When I use all 8 adapters CPU
load is between 4 and 12, never drops.
There is no problem with signal quality. In the cannels.conf is only
one multiplex. EPG scan take 2 seconds.
How can I find what VDR doing with not used adapters?
Maybe those adapters are not initialized and in the driver are bad
defaults.

CPU load debug, it is really strange. I tried to exclude IRQ storm,
but it is difficult to confirm it. :

Hi,
I have problem witch TBS6285 card
(http://www.buydvb.net/dvbt2-tv-tuner-pcie-c-12/tbs6285-dvbt2tc-quad-tv-tuner-pcie-card-p-93.html),
it was difficult to get it work. TBS drivers replace all media tree
in the kernel. After compilation I have problem with IR remote on the
current Hauppage Nova–T card. I decided to use only drivers for new
card with original kernel media build and it is impossible. Then I
changed IR receivers and connect it to the TBS6285. TBS have different
3V IR receivers.
And the end, VDR onscreen menu is unusable slow. 30s between key
presses. CPE load is more than 2, replay is OK, less than 0.2. Menu
parts, for example settings are good too.
I think it caused by function witch reading information from card.
Do you have any experience with this card or advice?
Thank you
Miloš
TBS driver : v140425
VDR: vdr-2.1.1
Kernel : Linux VDR2 3.12.20 #7 SMP PREEMPT Thu May 29 20:18:02 CEST

PS: Years ago I read in the mailing list, that VDR is not plug and
play, it is learning how computer works. I can confirm it and adding:
“VDR is my destiny or my curse” .
