Hello,
I'm really the one who have this problem? Something must have
been changed in the past. But the man page still states that in the
column WCHAN the function, in which a process are sleeping, will
be displayed. Either the function name (if System.map is available)
or the address of the function or a "-" if the process is running.
On my system, according to the man page of top, all processes are
running. That can't be right.

Where is /usr/bin/top looking for the System.map?

Thanks in advance.
