Zdravim,
byly v kenelu 2.6.30 a novejesim nejake zmeny ohledne pristupu k paralelnimu portu?
Mam tady radic kouwell KOUWELL 220N-2 od MOS technologies a ten funguje jen s jadry do 2.6.29. S 30,31,32 se sice zavede modul "parport, parport_pc", vytrovri se prislusne zarizeni /dev/lp1 a 2 po zavedeni modulu "lp", ale ty nefunguji:

, irq 7, dma 3 a to je integrovany na desce a funguje ve vsech kernelech.
To ze je parport1 zacpany je v poradku, protoze na nem neni nic poveseneho. Ale parport2 nic nehlasi a z tiskarny nic neleze.
Testovano na dvou pocitacich. Primarne s gentoo, kde se menil jen kernel se stejnou konfiguraci a 26,28,29 jsou funkcni.
Ubuntu 9.10 ma stejny problem. Starsi distra funguji (nejaky slax 2.6.9, finix 2.6.26).
Jde tedy nejspis o kernel bug? Nebo se zmenily pozadavky na konfiguraci?
