Errore in dmesg di "task kworker"

[Leandro Noferini <lnoferin@cybervalley.org>]

Ciao a tutti,

debian installata su raspberry 4 con sistema operativo su schedina sd ma
con tutte le varie directory in scrittura (home, var, opt) montate su
disco esterno.

Oggi mi sono trovato questo errore ripetuto più volte con tempi diversi
nel dmesg:

[3730483.156140] INFO: task kworker/0:2:32752 blocked for more than 120 seconds.

Mi dovrei preoccupare?
