Problem with TeVii S-470

[Mike Mironov <subscribe@darkmike.ru>]

Hello!

I have this card http://www.linuxtv.org/wiki/index.php/TeVii_S470

I try to use it under Debian Squeeze, but I can't get channel data from it.

I try to use drivers from 2.6.38, 2.6.39 kernels, s2-liplianin drivers 
with 2.6.32 kernel, last linux-media drivers with 2.6.32

With all drivers I can scan channels, but then a I'll try to lock 
channel I get some error in syslog (module cx23885 loaded with debug=1)

cx23885[0]/0: [f373ec80/27] cx23885_buf_queue - append to active
cx23885[0]/0: [f373ebc0/28] wakeup reg=477 buf=477
cx23885[0]/0: queue is not empty - append to active

and finally a lot of

cx23885[0]/0: [f42c4240/6] timeout - dma=0x03c5c000
cx23885[0]/0: [f42c4180/7] timeout - dma=0x3322b000
cx23885[0]/0: [f4374440/8] timeout - dma=0x33048000
cx23885[0]/0: [f4374140/9] timeout - dma=0x03d68000

In other machine this work under Windows. Under Linux I have same effects.

It's problem in drivers or in card? That addition information need to 
resolve this problem?
