Da hilft nur per Kernelparameter das NCQ zu deaktivieren und auf 3.0Gbps zu drosseln:

Code: Select all

libata.force=noncq,3.0Gbps

Den schwarzen Peter kann man hier sowohl den Firmware-Herstellern der Festplatten und SATA-Controllern, als auch den Linux-Devs zuschieben. Bis die sich alle gegenseitig auf eine gemeinsame Lösung geeinigt haben, werden noch einige Petabyte Daten durch dieses Problem verloren gehen...

Unter Windows existiert dieses Problem nicht, so dass es offensichtlich eine funktionierende Lösung gibt. Warum Linux diese nicht nutzt, weiss wohl keiner so genau...
