Hi !
As my last mail reached the list i suppose the two before didn't.
So:

You were right - my configuration was wrong. dunno exactly what was wrong.
>> fault ? There seem to be lots of "opt_smp.h" and <opt_smp.h> ....

You were right - everything is gone, compiling is just fine

I'm sorry (or better i really don't know what to say), but this problem is gone.
Maybe it was caused by my wrong configuration or making... could this be ?
I tried to get this error again, but it seems to be gone. Or is there some
connection to the one which i actually have right now (please, don't be
bothered)..
There is another problem concerning the root-filesystem:
panic(cpu#0): nobody wants to mount my root
I stopped over in configure(), autoconf.c but couldn't find out why
its not mounted...still trying. Hope i can solve this on myself.
If not, i'll have to ask tomorrow.
Anyway - hereafter is the output of mptable 2.0.4 as requested.
Bye
Gunther
