Hi Marcus,
The problems with 2031 were unfortunately never fixed. IIRC we were left
with the following problems:
1) tuner device sometimes missing in /dev/dvb/adapterX/ on boot (app.
20% of the boots, tested on 2 different machines)
2) needed to tune twice in case of freq change; the first time would
almost never give a lock (but sometimes it did strangely enough)
3) unstable signal, where signal would be lost after some time (hours);
this problem I never investigated thoroughly, because of 1) and 2) which
needed a solution first

at line #1648, does adding a msleep(20) or something around that order
help ? for your problem (2) mentioned
for (1) try using dst_addons=0x20 as module parameter.
You will need this patch as well (for fixing the dvb-attach). Apply this
patch first
http://article.gmane.org/gmane.linux.drivers.dvb/27792/match=
Alongwith one of the previous patches, commenting out one line for
DCT-CI cards
Unfortunately using dst_addons=0x20 for problem (1) does not seem to help.
I dug up 2 of my 2031 cards, and put them in a machine. First time after
boot, both cards did show a tuner; but the second time the tuner of
adapter0 failed as follows:
/dev/dvb/
/dev/dvb/adapter1
/dev/dvb/adapter1/frontend0
/dev/dvb/adapter1/ca0
/dev/dvb/adapter1/net0
/dev/dvb/adapter1/dvr0
/dev/dvb/adapter1/demux0
/dev/dvb/adapter0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/net0
/dev/dvb/adapter0/demux0
Here is how I loaded my modules:

Apparently there is some checksum failure reported on adapter0. However,
if I boot it again then there is 80% chance that the problem does not
occur .....
Now I will go and see if msleep(20) makes a difference for problem (2).
