[linux-dvb] KNC-1+Cineview CAM+Tuning Problems

i'm using a KNC-1 (stv0299) + cineview with a cryptoworks CAM + orf card. i'm
using the latest hg version of the dvb driver. the knc-1 is connected to
a technisat gigaswitch 11/20.
i'm experiencing strange tuning problems in conjunction with the CAM
inserted or removed. after using a streaming software, initializing the
CAM etc and terminating it, i cannot tune again, quite reproducibly.
i checked also with szap(1):
status 03 | signal a76e | snr 89ca | ber 00000000 | unc 00000000 |
status 03 | signal b038 | snr 8f3a | ber 00000000 | unc 00000000 |
after removing and re-inserting the cam, i almost instantly get a
status 1f | signal a8bb | snr c4bf | ber 00002d00 | unc 00000000 | FE_HAS_LOCK
status 1f | signal a641 | snr c4e6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
though, this is not reproducible. sometimes i have to remove/re-insert the CAM
2-3 times. sometimes i got a lock only after removing the CAM.
i can decrypt only one channel at once (it is definitely not a CAM initialization
problem). though, i know that the cryptoworks can decrypt at least 3 channels at
the same time (and the streaming software can also). i am doing this with some
other servers (but with wintv cards).
with kernels around 2.6.11 i had none of those problems even with knc-1 cards, though
i used a previous generation of the knc-1.
once, while ejecting and re-inserting the cryptoworks, i got that dmesg:
budget-av: cam ejected
budget-av: cam inserted
dvb_ca adapter 0: Invalid PC card inserted :(
i also got this once:
dvb_ca adapter 0: CAM tried to send a buffer larger than the link buffer size (65535 > 128)!
