I believe I posted a followup on this message but probably forgot
to do a group reply:
It turned out that I first thought it crashed only when I type ^T
while the dd was running. But this was accidently happening. Also
with bs=1m the system freezes (reproducably). Well, this is some
intermediate 5.2.1 so I will give it a try some time again when I have
a 6.x running.
