Hallo,
wenn ich ein bischen last (vorallem viel IO) auf meinem Rechner erzeuge bekomme ich immer diese Einträge in der log.
Die Einträge traten auf als ich mit 'shred' rumgespielt habe, sogar beim versuch shred zu mehr nettigkeit zu überreden ('ionice -c 3 nice -n 19 shred -fuvz /dev/sdXXXXX'):

Kann ich das irgendwie verhindern. Bzw. heißt das wirklich das hardware defekt sein könnte? Und wenn ja welcher Stick ist schuld? Ich habe 3 an einem USB-Hub hängen..
Ich habe auch nicht das gefühl, dass sich die Hardware ohne neustart des Treibers wieder erholt, zumindest nicht, wenn das passiert wenn gerade aufgezeichnet wird (mythtv).
Ach ja, wie kann ich denn den ISO/BULK TRANSFER MODE testen?
benutzt wird der Development treiber..
