Hi,
I'm running Ubuntu server 9.04 amd64 with kernel 2.6.28-11-server kernel.

When running s2-liplianin with my Azurewave AD-SP400 CI (Twinhan 
VP-1041) it stops working after a while and
if I do a dmesg I can see this every time it stops working. Sometimes I 
have to poweroff my computer because a reboot
will not fix the problem.

In this case it stopped working and then I tried to szap-s2 on the 
loopback device, hence the loopback messages.
And in this case a restart of sasc-ng solved the problem.

Then I tried the initial mantis trre mantis-v4l I have to modprobe 
mantis to get it to load and the first channelscan with scan-s2
did not work, the second time worked and third and above did not work. 
Switching back to s2-liplianin it works again but stops working
after a while. Today I used szap on a DVB-S2 channel and after that it 
stopped working again.

I have had dvbloopback loaded and sasc-ng running but my tuning was on 
adapter 0 (not the loopback device)

Does anyone have any thoughts or clues about this. It feels like the 
driver are more unstable than about 6 month ago or it is
something with my Gigiabyte motherboard.

Regards
Claes
