[linux] oopsujuci system

[dex]

da sa zakopilovat debug podpora a potom je na to celkom vesele howto 
debug oops message ked das do googla
tusim niekde pod lkmd.org linux to pisal tusim ako prvy su tam hlasky 
ktore asi nepotetsia :--P
ale zistis ak si na to trufnes ze kde ti to pada nieje to easy
kedze je to opteron ja by som si tipol ze nejaka chyba SMP alebo problem 
s vlaknami
btw nemozes to skusit vylucovacou metodou vypnut niektore sluzby

btw ma to grsec/pax ?????
