Now the situation is:

ACPI enabled,   APIC enabled:     works fine
ACPI disabled,  APIC disabled:    not recognized
ACPI disabled,  APIC enabled:     not recognized
ACPI enabled,   APIC disabled:    not recognized

I also encountered occasional "Panic: failed to create swap zone" when
CPU #1 was launched just before the disks get mounted. Could that be
related?
