I doubt this has anything to do with SL4, as hardware is usually responsible
for these types of problems.

For example, I have around 10 SL42 machines which hang off an ATen 16 port kvm
switch. Most of the servers work fine, while others like the older Compaq
Proliants (dl360's etc) and Dell Poweredge servers don't work well at all
(actually, the poweredge doesn't work at all, but it doesn't freeze the
system, just the keyboard doesn't work).

The older proliants work, but I can't press the arrow keys on the console
without getting the errors like:

atkbd.c: Unknown key releasd (translated set 2, code 0xe0 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.

All the newer machines (hardware) work fine and don't give any issues.

Michael.
