Hello !

I'm trying to work with KNC1 card with CI slot and Viaccess CAM module.
I'm using latest v4l-dvb source tree from "hg clone
http://linuxtv.org/hg/v4l-dvb ".
Card is detected correctly:
saa7146: register extension 'budget_av'.
saa7146: register extension 'dvb'.
DVB: registering frontend 0 (ST STV0299 DVB-S)...
ACPI: PCI Interrupt 0000:02:03.0[A] -> GSI 23 (level, low) -> IRQ 17
saa7146: found saa7146 @ mem f8888000 (revision 1, irq 17)
(0x1894,0x0016).
saa7146 (0): dma buffer size 192512
DVB: registering new adapter (KNC TV STAR DVB-S)
adapter failed MAC signature check
encoded MAC from EEPROM was
ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff
KNC1-1: MAC addr = 00:09:d6:65:9c:67
DVB: registering frontend 1 (ST STV0299 DVB-S)...
budget-av: ci interface initialised.

szap can lock the card to transponder:
status 1f | signal cf6f | snr c936 | ber 00005b00 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal cf71 | snr c89d | ber 00000000 | unc 00000000 |
FE_HAS_LOCK

FTA channels wotking correctly.

When I'm requesting CI+CAM with the command:
libdvb-0.5.5.1 # ./cam_set -a 1
Found 1CAM(s)
CAMInit: CI link layer level interface type
Using /dev/dvb/adapter1/ca0
Found 0 slots. caps.slot_num:1
CAM: Viaccess, 01, 0500, 0500


following message is shown:
Sep 28 21:23:28 streamer2 budget-av: cam inserted B
Sep 28 21:23:30 streamer2 dvb_ca adapter 1: DVB CAM detected and
initialised successfully

but card is loosing lock:
status 1f | signal d0bd | snr c921 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status 00 | signal 0000 | snr 3cf0 | ber 0000b184 | unc 00000000 |
status 01 | signal 957a | snr 7fd1 | ber 000033c9 | unc 00000000 |
status 01 | signal 94c2 | snr 7faa | ber 0000341a | unc 00000000 |

And don't want to lock again. What is the problem ? Is anyone have any
idea how to solve this problem ?
Thanks !
