FYI (2.4.4) on a HP Netserver LD Pro

FYI (2.4.4) on a HP Netserver LD Pro

[Ulrich Windl]

Hello,

I have some odd boot messages (new since switching from kernel 2.2 to 
2.4) for the HP Netserver LD Pro (Pentium Pro 200MHz). I'd like to know 
if there is a hardware or configuration problem, or whether it's "just 
normal" (the "reserved twice").

It's "just normal".  The MP-table parsing code reserves space
for the MP table and then parses the table.  But the table
also reserves its own space.
