Witam.
Mam nastepujacy blad w /var/log/messages.(ponize tresc) Po jego wystapieniu pozostaje tylko twardy reset komputera, bo wogole nie reaguje.Na ekran wyrzucane sa bardzo szybko jakies komunikaty ale nie sposob ich przeczytac. 
Czy ktos wie co moze ten blad powodowac, albo jak moglbym przesledzic jego powod? 
Prosze o pomoc.
Pozdrawiam,
Tomek Kopczyński
