Asi chyba v zonovani nebo konfiguraci pole :(. Nema to nejake rozhrani/sw,
kterym se da zkontrolovat konfigurace? Co je to za pole?
Mozna by neco vic napovedelo pridani

/etc/modprobe.conf (myslim, ze je to nakonfigurovane primo instalatorem
 RHEL4; jedine co se tam pridavalo je ql2xfailover=1, ale v tehle verzi
modulu (8.01.04-d7) to stejne nefunguje, resp. paramater uz neni
rozpoznavan))
