We do not have enought information on the systems to determine if this is the correct behaviour (it can, if no filesystem mounted allows discards, e.g. if you only have on /, encrypted, and discards are not allowed). Can you please provide more information on the systems, dmesg outputs, partition layout, filessytems and montpoints. Regards, Salvatore
