I guess I'm not the only one who is trying to be an a**hole :)

Ask md-raid developer [1] because he states about the bug there (and
also somewhere else)

Go find bug number yourself. If you have any counter-information,
share it here, correct me and let us all learn.

For all others, %60-70 of raid10 configurations may fail one drive
with current raid10 module shipped with CentOS5 because of being
somehow old.
