I have 3 identical Sun Blade with 16 used CPU-Slots (each) where each can
has two CPU's and shared memory between them and this machine machine
does not boot with a NON-SMP Kernel, even if I remove 15 CPU-Cards.

Since I do not know, how many CPU-Slots you have, but do you have tried
to run the machine with ONLY ONE CPU-Card?
And no, I can not try another Kernel on one of those machines since
they are in production and running 24/7. (The last Kernel-Update was
the Hell since one of the two Slave-Machines where I have tried the
update was very hard crashed and has the entired Filesystem of over
20 TByte to be marked corruped -- not realy funny!)
Thanks, Greetings and nice Day
