Jelikoz mi jeden vykuk odpalil 4GB disk a je to precijen 366MHz celer,tak kompiluji jadro na vykonejsim PC (Sempron-gentoo) a pak ho kopiruji na toho celera.Snazil jsem se rozjet tuto kartu podle clanku zde na foru,ale marne. Kdyz nactu modul, tak to vyhodi toto :-/

 Segmentation fault

Vypis zacina driver unloadet, protoze jsem predtim zkousel jine ovladace oznacene jako Prism2neco,modul vznikly z kompilace byl v poradku, pekne se nacetl a vytvoril wlan0, ale to bylo asi tak vse, iwconfig oznacil wlan0 jako non wireless a nemohl jsem nic nastavit (krome ifconfigu).Mno a podle navodu vzdy dorazim k vypisu vyse po nacteni modulu. Po nacteni zacne karta vzadu blikat(to plati u obou modulu).
Po snaze odpojit modul zahlasi,ze zarizeni je zaneprazdneno, po zadani prikazu ifconfig muzu cekat na vypis 10let
Jinak se to snazim rozjet na debianu (woody-stable), pouzivam wireless-tools27. Myslim, ze s napajenim PCI by asi problem byt nemel(zas tak stara deska to snad nejni :-/ ). Diky vsem

Tak tento dotaz je opravdu zbytecny. Jak jsem predpokladal, problem byl v celem systemu => spousta baliku nebyla nainstalovana vlivem preruseni instalace (to jsem si vsak neuvedomil, pac jsem ten debian instalil asi pred 2 mesici). Jednoduse jsem nainstalil znovu a ciste debian, nechal jen veci, co potrebuji, nainstalil zdrojaky k jadru atd., najednou slo vsechno pekne kompilovat a wifina uz pekne slape . Skoda, dva dny zbytecny prace :-/ . Mozna to bylo i tim jadrem, pac tentokrat jsem ho kompiloval primo na tom PC (radsi).
