HTT/SMP does not start 2nd processor

I have two P4 machines here, both with processors supporting hyperthreading,
and running identical SMP kernels from 5.4-RELEASE. One runs with two
logical processors and the oother doesn't. This has been puzlling me all
day.

On the machine where the second CPU does not start up, HTTP is
enabled in the BIOS, and I get the following in dmesg:

CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (2992.52-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf29  Stepping = 9
 
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,C
MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Hyperthreading: 2 logical CPUs
real memory  = 536739840 (511 MB)
avail memory = 515579904 (491 MB)
MPTable: <COMPAQ   Workstation >
ioapic0: Changing APIC ID to 1
ioapic0: Assuming intbase of 0
ioapic0 <Version 2.0> irqs 0-23 on motherboard

On the one which starts up the 2nd CPU the equivalent part is:

CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2392.04-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf29  Stepping = 9
 
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,C
MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Hyperthreading: 2 logical CPUs
real memory  = 536301568 (511 MB)
avail memory = 515137536 (491 MB)
ACPI APIC Table: <DELL   WS 450 >
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  1
ioapic0: Changing APIC ID to 8
ioapic1: Changing APIC ID to 9
ioapic2: Changing APIC ID to 10
ioapic0 <Version 2.0> irqs 0-23 on motherboard
ioapic1 <Version 2.0> irqs 24-47 on motherboard
ioapic2 <Version 2.0> irqs 48-71 on motherboard

So both are reporting 2 logical CPU's, but only the second is then
detecting this as a multiprocessor system. I notice that one syas
it is using an ACPI APIC table and the other (that does not start) is
just finding an MPTable. That seems to be the difference between them.

Does anyone have any suggestions ? I dont really understand how this
stuff is detected, so I am not sure how to sart digging into this. It
is obviously finding a dual CPU processor, so why isn't it then detecting
it as a multiprocessor system ?

*puzzled*

Make sure the acpi kernel module is being loaded on startup.  See
acpi(4).

HTT/SMP does not start 2nd processor

Hi,

I have problem with 5.4-RELEASE on Dell Power Edge 1600sc (previously 
5.2.1 was running on it for 1.5 year - no problems). At first 
I thought it might be problem with BIOS, but I have upgraded it
to A12 (latest one on DELL's site). There is problem, whenever
I enable APIC I get this lock (no dump :( on swap partiton), so
I have writen it down:


Fatal trap 12: page in fault while in kernel mode

CPUID = 2; APIC ID = 02

Fault virtual address   = 0x24
Fault code              = supervisor read page not present
Instruction pointer     = 0x8:0xc050c3df
Stack pointer           = 0x10: 0xE94AAc5C
Code segment            = base 0x0, limit 0xfffff, type 0x1b
                         = DPL 0, PRES 1, DEF 32,1 GRAN 1

Processor eflags        = resume, iopl = 0
current process         = 64 (swi 5: clock sio)
trap number             = 12
panic: page fault
cpuid = 2

Without APIC everything seems to work fine...
