This is a dual xeon system with hyper threading enabled, so there should
be 4 cpus

Hmm, perhaps ACPI teleported it (and converted it to an AMD64) into Dave Jones'
machine? (see the other thread about the `extra' CPU ;-)

Interesting...

Can you try sending dmesg output too?

here it is, but this time all 4 cpus are detected. Later I will try some reboots
and check if I can reproduce the problem.

Next time it happens, please send dmesg, and also 

cat /proc/acpi/processor/*

ls /sys/devices/system/cpu

would be useful.. Dont know if bios disabled one thread for some reason

2.6.16.1 lost cpu, was: 2.6.16-rc5 'lost' cpu

shouldn't that be "Booting processor 2/_4_ eip 2000"?

I agree the message is not clear.. but the number is the APIC id of the cpu
its trying to boot..


ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled)
Processor #0 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x02] lapic_id[0x06] enabled)
-----------------------------------^^^^^^^

Processor #6 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x03] lapic_id[0x01] enabled)
Processor #1 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x04] lapic_id[0x07] enabled)
Processor #7 15:2 APIC version 20

Ok i've seen that about 2years ago on a similar Xeon system, it was hard 
to reproduce as it only happened on the occassional boot i was thinking of 
making the processor startup delays longer but could never get it to 
reliably fail. The system is still running today.

It decided that the first CPU had only one sibling, sounds like an ACPI 
issue, if I had to place a bet I would lean to the hardware/BIOS not 
admitting to that 2nd sibling.
