Hi,
Something strange is going on. The server in question is dual P-III/850 on
Intel 440GX+ board. Neither 2.4 nor 2.2 kernel doesn't see second cpu, but some
APIC error. What's the problem? Here dmesg goes:

Looks like your MPS table is lacking. What happens if you do
"phys_cpu_present_map = 3" at the end of smp_read_mpc()
in arch/i386/kernel/mpparse.c ?
