I have disabled 2nd adapter by default recently due to problems.
Enabling 2nd FE causes driver sensitivity problems seen as mosaic pixels
in picture. I don't know if this problem exists all devices... 2nd
adapter can be enabled with module param, modprobe dvb-usb-af9015
dual_mode=1 enables it. I will of course enable it by default when
problem is found.

I did small change for GPIO setting to avoid warmboot/coldboot problem
you have seen. Please test.

I also changed mxl5005s tuner RSSI enabled - Jose Alberto has found that
old mxl5005 driver was using it always enabled and therefore better
performance for his hardware.


Thank you kindly Antti.
I will try the above and let you know.
Regarding the pixelation:
I have experienced it, but my dvico dual digital 4 rev 2 in the same machine was doing it as well.
I bought a distribution amp as my 2 splitters (4 way and 3 way) introduced about 12db attenuation.
My signal level has gone to about 75% up from 62% and the dvico is not pixelating anymore.
Will try the kworld/afatech from the above http://linuxtv.org/hg/~anttip/af9015_test in about 10 hours when I get home and
will let you know about the warm booting, dual tuners as well as the pixelation and whether teh distribution amp has eliminated it.
Thanks muchly
