nefunkcni firewire (IRM is not 1394a-2000 compliant)

[Pavel Novák]

Zdravím,
bez problému jsem připojoval svůj externí disk k notebooku přes firewire
až najednou to přestalo fungovat. A v dmesg si mi začaly objevovat divné
hlášky "Current remote IRM is not 1394a-2000 compliant, resetting..."

Po tomhle výpisu se mi sice v /dev objeví sda ale při mount vytuhne...,
častější je ovšem výpis tohoto typu:

Takze se musim opet pripojovat pres usb, který mi jede rychlosti usb1 :(

Tesim se na kazdou radu...
