Αργό boot (ubuntu 12.04)

[Antonis Sidiropoulos]

Γεια σας,

Σε ένα λαπτοπ έχω ubuntu 12.04
όμως έχω την εντύπωση ότι bootάρει πιο αργά απ' ότι θα έπρεπε...
To dmesg δείχνει ένα χρονικό κενό 40 secs...
καμία ιδέα για το πως μπορώ να κάνω λίγο debugging ή τι μπορεί να φταίει?
Παραθέτω κομμάτι από το dmesg:
