problemy z bt848 na jadrach 2.2.x (dlhe)

[bl]

Zdravim!

Mail je velmy dlhy lebo dany pocitac nemam u seba tak je v nom vsetko co
som povazoval za dolezite.

Mam starucku bt848 kartu bez tunera. lspci -v o mojej karte pise:
--------------------------------
00:09.0 Multimedia video controller: Brooktree Corporation Bt848 TV with
DMA push (rev 12)
       Flags: bus master, medium devsel, latency 64, IRQ 10
       Memory at e3001000 (32-bit, prefetchable)
--------------------------------

Problem je z pozeranim i z capture. V jadrach bol vzdy novy i2c co by
mohlo driveru vadit ale z dokumentacie som nadobudol dojem ze je nato
myslene. Skusil som viac moznosti a to konkretne tieto:

jadro 2.2.19, i2c stack ako modul lm_sensors ako modul bttv ako modul:
       -xawtv blblo pri prezerani i pri capture pri akejkolvek zmene 
        nastavenia ci polohy okna obraz zmizol a bolo treba znova 
        nastavit spravny vstup.

nastavenie modulu: bttv pll=1 (inak je zly obraz)

-------------------
jadro 2.2.21 i2c stack ako modul lm_sensors ako modul bttv v jadre:
       -xawtv pri prezerani OK. capture len do mjpeg ale nie vzdy sa 
        podarilo. ine nastavenia vyhlasovaly chyby.
       -nubsvideo nic nenacapturovalo skor budilo dojem ze je 
        zaseknute.
       -mplayer prehraval tv vstup len z nastavenim vstupu ako rgb24 
        inak sa zasekol.

-------------------
jadro 2.2.21(patch i2c i lmsensors) i2c stack v jadre, lm_sensors v
jadre. posledny driver pre bttv a jadra 2.2.x (vyzaduje toto nove i2c):
       -xawtv pri prezerani bez problemov. capture do cohokolvek ale 
        vysledkom je video plne cisto modrich framesov. z capture som 
        mal dojem ze straca velmy vela framesov.
       -mplayer sa tvari spokojne ale zobrazuje bud cisto bielu alebo
        ruzovu obrazovku (zalezi na nastaveni vstupneho formatu)

i2c-algo-bit v jadre.
nastavenia modulov v modules.conf:
------------------------------
alias char-major-81-0   bttv
options bttv            card=0 pll=1 radio=0 tuner=4
options tuner           type=4 debug=1
options btaudio         debug=1 irq_debug=1

--------------------------------

p.s. to dlhe zaseknutie je podla dokumentacie zapricinene nepritomnostou
tunera malo bi sa odstranim nastavenim "options i2c-algo-bit bit_test=1"
v modules.conf ale ja mam tento modul v jadre da sa to i tam nejak
nastavit? v dokumentacii co je v balicku i2c som nic nenasiel a ani
zdrojovi kod mi nic nenapovedal.
