Hmmm reading the kernel-parameters again and again ...

<QUOTE>
        memmap=nn[KMG]$ss[KMG]
                        [KNL,ACPI] Mark specific memory as reserved.
                        Region of memory to be used, from ss to ss+nn.
</QUOTE>


nn would be 0x18690000   or ~409MB
ss would be 0x10000      or 64k

quite big hole ???

I'm not in front of the faulty box, but something is wrong there ...

Best regards,
Jan-Simon
