Hi!

Very interesting:

Without the SMP option, without acpi, I can boot verbose, and it works.

With apci, the machine locked - the same way as with SMP+acpi. The only 
difference is, that with 'options SMP' the last lines are:

Table 'FACP' at 0xfdf20
Table 'APIC' at 0cfdf94
MADT: Found table at 0xfdf94
MP configuration Table version 1.4 found at 0xc00f0000
APIC: Using the MADT enumerator.
MADT: Found CPU APIC ID 0 ACPI ID 1: enabled
SMP: Added CPU 0 (AP)
MADT: Found CPU APIC ID 1 ACPI ID 2: enabled
SMP: Added CPU 1 (AP)

and without 'options SMP' :

Table 'FACP' at 0xfdf20
Table 'APIC' at 0cfdf94
MADT: Found table at 0xfdf94
MP configuration Table version 1.4 found at 0xc00f0000
APIC: Using the MADT enumerator.
MADT: Found CPU APIC ID 0 ACPI ID 1: enabled
MADT: Found CPU APIC ID 1 ACPI ID 2: enabled

I tried with acpi and without apic, too. Of course, it worked.

What can I do now?
