I'm in a state when the boot messages are:
saa7146: found saa7146 @ mem ffffff0000052000 (revision 1, irq 16) 
(0x13c2,0x1011).
DVB: registering new adapter (TT-Budget/WinTV-NOVA-T  PCI).
adapter has MAC addr = 00:d0:5c:23:34:49
DVB: registering frontend 0 (Philips TDA10045H DVB-T)...


Then when I want to watch TV with mplayer with command:
mplayer dvb://station
I've got no other dmesg output about frontend, last messages from player 
are:
code taken from dvbstream for mplayer v0.4pre1 - (C) Dave Chapman 2001
Released under the GPL.
Latest version available from http://www.linuxstb.org/
dvb_tune Freq: 506000000

and I can wait and wait ...

I'm sure that the frequency and stations are set right, I'm sure about 
antene system (watching with old kernel just fine)
Amazing is that sometimes it just starts to work with other reboot 
without any changes.

Any ideas whats wrong with 2.6.10 kernel?
I'm using 64bit system with Gentoo linux, my latest kernel is 2.6.10-r4.

Thanks for reply
