On the 4P box, 2.6.32-git10 boots and shows 4 CPU's, 2.6.32-git12 boots
and shows 1 CPU, 2.6.32-git15 to 2.6.33-rc1-git3 1 CPU and lots of oops,
continues with something like "Sending NMI interrupts to CPU's",
[udev] unexpectedly returned with status 0x0100
[udev] failed while handling /devices/pci000:00 -----etc--- same for
other devices.
Unable to capture via serial console as USB doesn't come ready.

On 2P laptop, up to 2.6.33-rc1 boots, 1 CPU and boot option "acpi=noirq"
needed, without it boot hangs, I think from 2.6.32-git15.
Building kernels, I have used the .config from previous kernel and
"make oldconfig".

Same problem with linux-next 20091224, only one penguin showing during boot.
To get linux-next to boot I had to use kernel command line "acpi=off",
without, it shows the failures noted above.
When booted /proc/cpuinfo shows only 1 of the 4 CPU's.

Just made some changes to .config, shall try building on the 2P box with
old .config to see if it's a config problem -- doubt so as the configs
were fine with earlier kernels.
Attaching the .config diff.

I decided to use the config from the openSUSE kernel as the basis of a

see if anything stands out.

Something is weird on the 2P box. Using the openSUSE kernel
2.6.32-3-default and early 2.6.32-git kernels on the 2P box, I see 2
processors. Same if I boot from the install DVD.
Using 2.6.32-git10, 2.6.32-git15, 2.6.33-rc[12] the box hangs solid at
various places during boot.
When I first booted up 2.6.33-rc2 after using the openSUSE 2.6.32-3
.config as the basis for "make oldconfig", the kernel booted fine with 2
CPU's, second and subsequent reboots, it locks up solid.
Later I shall try to get some output from a serial console.
tindog:/usr/src # uname -r
2.6.32-git1-smp
I shall also progress through the kernels to see exactly which
introduces the problem where a kernel will boot one time and not other
times and why only one CPU shows when those kernels boot.
Regards
Sid.

Sid,
If the kernel boots properly as of -rc2, then I would not worry
so much that it was broken at some point during the merge window.

However, if it is still broken and you need to bisect back
into -merge to find out what caused it... note that
booting with "acpi=ht" may be a useful tool. For this
option will boot just enough of ACPI to enumerate processors,
but no more. (Of course if this option doesn't boot with
the previous working kernels, then alas, it will not be useful here)

2.6.32-git1 boots OK with 2 CPU's.
2.6.32-git2 boots with "acpi=ht" but only one CPU appears.
With 2.6.32-git2 booted
# git bisect bad

Without "acpi=ht" there is a solid lock up

Right, your local apic is not found, ie this is missing
in the 2.6.33 dmesg:

ACPI: Local APIC address 0xfee00000

Strange, as CONFIG_X86_LOCAL_APIC=y

That is the case for >2.6.32-git1. As I could get some early 2.6.32-git

I checked the BIOS and it's the latest available.

2.6.33-rc2-git5 booted and showed both CPU's on first boot, on
subsequent boots it hung at HDA irq 22 as it did on earlier kernels.
