Quick responses once again, thanks much to Alan_at_nabeth
and Oisin McGuinness. I used their ideas, and quickly
was able to locate the problem.
Problem seems to be with gnu commands, whose path has
higher presendence in my $PATH. So, all the example
commands have been built a while back.....i guess back
in 4.0D and we are now on 4.0G, using update install.
They have not been rebuilt.
Using absolute path names to commands such as who and
ls, work OK. So, its true that some emulation has to
take place to use the gnu commands built in older OS
version to work in current OS as stated by the
repliees.
So maybe ssh supresses these echos?
I have to rebuilt (infact upgrade) these gnu products
eg.ls, who, mv, chown, mmmhhh, seems like all of
them!! I guess Easier way out is simply change my
$PATH, and instead use OS binaries.
THIS is what the repliees had to say:

I believe the message indicates that a command is
executing
an instruction that has to be emulated on a
particular
platform. The command is given in the angle
brackets.
The process id by pid=, the virtual address by va=,
the program counter by pc= and the instruction by
inst=. You'd probably need an architecture guide to
translate the bits to something useful.
This isn't the sort of thing that should happen with
the
distributed utilities. They should be compiled in
such
a way that they don't depend on the instructions
offered
by later systems. Custom (GNU for example) versions
of
these command could have been compiled to assume one
of
the more recent models, but you're running them on an
older model.
What model you're on, would be an interesting bit of
information.

This is almost certainly the result of running on an
older machine
(check cpu type using psrinfo -v), e.g, EV4 or EV5,
code which has been
built (say with gcc) on a newer cpu (EV5.6) or
whatever. If one has
not taken care when configuring gcc to make sure it
produces
code for generic alpha, and not ev5.6 or whatever,
then running
applications
built with this on an older alpha results in the OS
emulating the
missing instructions. (man cc and see discussion on
emulation).
It is very annoying, and the binaries are also running
much more slowly
in such a mode.
Solutions: i) get rid of the old machines, or ii)
rebuild the offending
software
either universally, or just a special version for your
old machine.
