[linux-dvb] mantis and dvb_ca adapter 0: CAM tried to send a buffer larger than the link buffer size (16384 > 128)

[Dmitry Podyachev]

How to look which layer of CI available for mantis (VP-1034  Mantis Rev 
1 [1822:0014] )
modprobe stb0899
modprobe mantis

DVB: registering frontend 0 (Fujitsu MB86A16 
DVB-S).                                     ..

kernel: mantis_ca_init (0): Registered EN50221 device

zap_ca and gnutv don't work properly with CAM:
/hg/dvb-apps/util/gnutv # ./gnutv -adapter 0 -caslotnum 0 -channels 
/srv/mantis_c/sport.conf -secfile /srv/mantis_c/sec.cfg -secid c10750 
-cammenu

[linux-dvb] mantis and dvb_ca adapter 0: CAM tried to send a buffer larger than the link buffer size (16384 > 128)

[Dmitry Podyachev]

with "open" channel situation little bit different:
./zap -adapter 0 -caslotnum 0 -channels /srv/mantis_c/sport.conf 
-secfile /srv/mantis_c/sec.cfg -secid c10750 'open_channel'
Using frontend "Fujitsu MB86A16 DVB-S", type DVB-S
status SCVYL | signal ff76 | snr ff12 | ber 00000000 | unc 00000001 | 
FE_HAS_LOCK
CAM Application type: 01
CAM Application manufacturer: 0500
CAM Manufacturer code: 0500
CAM Menu string: Viaccess
CAM supports the following ca system ids:
  0x0500
Received new PMT - sending to CAM...

and after unload/reload all dvb* modules  when modprobe mantis.ko it 
kernel panic.
If anybody has experience with dvb_ca - help please with advice
