What's the output of the following commands:

lsmod|grep -i dvb
lsmod|grep dd
dmesg|grep DDBridge
dmesg|grep -i dvb
kernel uname -r
dkms status
modinfo media
modinfo ngene
modinfo dvb-core

I can't say right now since the system is in use (windows).
I'll post that the next time I can play around this weekend.

But as far as I can remember, it was using with ddbridge drivers 0-9-31-internal,... (the one in the 4.15. kernel)
Before that I was using a dddvb-dkms build which was slightly newer 0.9.32... I believe. That also had the same problem, but at least showed something in SNR and signal strength.
That was also what used to work when the system was still running under ubuntu 1604.
I removed dkms stuff to try the built in drivers, but again poll-timeout...

I don't need ngene (anymore), the card is a V6 with a piggyback additional 2 Tuners (4 in total).

I think I'm doing something wrong, since I've already read of people running ddbridge on 1804, but then, it's still pretty new.

Here goes:

I just noticed that msi ints were back on again. IIRC that never really worked, so I set them back to off, watching it right now.

Now tvheadend just crashes when I try to map a service. Probably a different problem...
I give up for now.
back to windows (sigh)

I'm using kernel 4.19.8 on ubuntu 18.04 and that's working fine, so probably it is a driver issue with the original kernel.
