Mentre stavo accedendo a un file system via NFS, improvvisamente, si è bloccato tutto.
Al di là del fatto che ho dovuto lanciare (dopo aver spento brutalmente) fsck manualmente e non vi dico la montagna di errori che venivano fuori, i log non sono molto rassicuranti:

Code:

come suggeriscono altrove:
o abiliti
Code:
CONFIG_DEBUG_SLAB


oppure provi a vedere su google se trovi qualcosa di più vicino al tuo problema...

E' stato un evento isolato o ti accade ogni volta?

No, direi che si è trattato di una caso isolato.
