I've been running this script (with the mentioned version of mdadm) and
nothing has gone wrong.
The 'dd' keeps reporting read errors of course, as does the kernel, but not
crash or freeze or anything.
What exactly happens when you run it? Do you get a kernel stack trace at all?
Can you post logs showing where it goes wrong?
Thanks,
NeilBrown
