[linux-dvb] KNC1 DVB-C (MK3) w/ CI causes i2c_timeouts

A few days ago I swapped my old KNC1 TV Station Plus for a newer revision TV
Station (MK3; non plus) which was slightly modified by KNC1 to better handle
my cable provider's QAM256 modulated signal. So far the BER value has dropped
to zero and things seem to work fine except that I now get the following msgs
from time to time:
"saa7146 (0) saa7146_i2c_writeout [irq]: timed out waiting for end of xfer"
"DVB: TDA10023: tda10023_readreg: readreg error (ret == -512)"
Also infrequently, it takes a few more extra seconds to tune to another
channel after I have been switching around a lot. It's not related to any
specific channel and happens (more or less) totally randomly.
All this worked fine with my old card which had a tda10021 and besides that
was mostly the same. I haven't changed anything software-wise between the
swap, so it's somehow related to the new card.
By the way, I am using a mercurial checkout from 20 Apr 08.
If anyone can help me out on this one, I'd greatly appreciate it.
Here some infos:
