Hi!
I've got a Dell WS210, 2-processors system (2 P-III/550). (Last BIOS,
version A10.) As an SMP system, it works prefectly:
$ fgrep -i cpu /var/run/dmesg.boot
cpu0 BSP:
cpu0 on motherboard
cpu1 on motherboard
SMP: AP CPU #1 Launched!
cpu1 AP:
But if I switch on acpi (set hint.acpi.0.disabled=0 on loader prompt),
it locks. Here are the last lines from a verbose ACPI- boot:
Preloaded elf module "/boot/kernel/if_xl0" at ....
snd_cmi
sound
snd_mss
usb
ugen
ulpt
umass
agp
ng_ubt
r128
smbfs
libmchain
libiconv
acpi
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 now nothing more. I don't know anything about ACPI/SMP, but
without acpi, the first processor is BSP, and the second is AP. With
acpi, both of them are named AP.
Is it possible to use both of the processors, and the ACPI
implementation on this machine? By the way, OS version is 5-STABLE from
tomorrow (June 27, 2005, CEST) morning.
Bye,
