This is a problem which I'm seeing for a loooooong time now.
I've been geeting this correuption a while back too - look at the mailing
list archives. The problem seems to be cache corruption as far as I can
see. Since Ralf checked in some small fixes for the cache handling it's a
bit better - but not completely fixed.
The Problem is also tracked on the buc tracker btw (#5) .
I have seen this only when copying from one harddisk to another.
Especialy if one wants to copy the kernel sources it will messup.
