Thank you, Martyn!
I remove my changes from linux_2.6.32+2.6.33-rc3.bb and I build was 
successful but don't boot with image :(  - all hangs

I think I had this problem as well when compiling for a i586-generic
(infact i686-generic and x86 as well).

All the kernel bitbake files contain DEFAULT_PREFERENCE = "-1" and the
bitbake file for the newest kernel (linux_2.6.32+2.6.33-rc3.bb
<http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/linux/linux_2.6.32+2.6.33-rc3.bb>
I think) was failing for x86.

I modified linux_2.6.32.bb
<http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/linux/linux_2.6.32.bb>
from:

|DEFAULT_PREFERENCE = "-1"
|

to:

|DEFAULT_PREFERENCE = "1"
|

and was able to build (though I haven't got around to testing the
resulting kernel yet...)

At what point does it hang?

At a guess (as you haven't provided any specifics) I'd guess that you
need to look at the kernel configuration.

When I try boot image in qemu I see
booting kernel ... and nothing.

Hello,

right

Setting DEFAULT_PREFERENCE_yourmachine = "1" is not enough: you have
to provide a specific defconfig for your machine, in a subdir of
linux-2.6.32+2.6.33-rc4
Actually only spitz machine has one...I suppose you are building using
default defconfig.

I'm afraid I have no experience with using qemu, so I don't think I can
really make any suggestions at this point.

Did you set the console properly. i.e. -append "console=ttyS0" on qemu
invocation ?

Re: Adding a new Machine question

After some conf changes I get unknown device sda - but I look at kernel 
config seems all is ok

Adding a new Machine question

[Perepelica Alexander]

Hi!
I have problem with configs for new x86_64 machine.
How I read in manual I need set next vasiables
1. TARGET_ARCH
  TARGET_ARCH = "x86_64"
2. MACHINE_FEATURES
 MACHINE_FEATURES = "kernel26 screen keyboard pci usbhost acpi ext2 x86"
 MACHINE_EXTRA_RRECOMMENDS = " kernel-modules"
3. PREFERRED_PROVIDER_virtual/kernel
 PREFERRED_PROVIDER_virtual/kernel = "linux"
 And now when I build  helloworld-image all is ok i get my RFS image.
But when I try build bootstrap-image I got error
"  no such directory asm-x86" but I see dir with name "asm-generic" and
name of machine conf file is x86_64-generic.conf.
So, I don't understand what I do wrong?

x86_64-generic.conf
# Released under the MIT license (see packages/COPYING)
#@TYPE: Machine
#@NAME: x86_64
#@DESCRIPTION: Machine configuration for a generic x86_64 machine

TARGET_ARCH = "x86_64"

#PREFERRED_PROVIDER_virtual/kernel = "linux"
PREFERRED_VERSION_gcc = "4.4.2"
KERNEL_IMAGETYPE = "bzImage"
GLIBC_ADDONS = "nptl"
GLIBC_EXTRA_OECONF = "--with-tls"

IMAGE_FSTYPES ?= "ext2.gz"
IMAGE_DEVICE_TABLES = " \
  files/device_table-minimal.txt \
  files/device_table_add-loop.txt \
  files/device_table_add-scsi.txt \
"
MACHINE_FEATURES = "kernel26 screen keyboard pci usbhost acpi ext2"
MACHINE_EXTRA_RRECOMMENDS = " kernel-modules"
TARGET_CC_ARCH = "-m64"
BASE_PACKAGE_ARCH = "x86_64"
FEED_ARCH = "x86_64"
#PACKAGE_EXTRA_ARCHS += "x86 i386 i486 i586 i686"

to:

and was able to build (though I haven't got around to testing the
