Subject: HDA Intel Audio hang on boot

Renaming this bug as the "only 1 CPU" bug has been fixed, but the hang
at HDA remains.
I shall plug in a SB Audigy and see if it will boot with that.
By disabling the on-board HDA Intel audio in the BIOS, the system boots.
tindog:~ # uname -r
2.6.33-rc4-smp
On 2.6.32-git1 which boots, hwinfo shows:-
  oss.card_id = 'HDA NVidia'
  oss.card_id = 'HDA NVidia'
  oss.card_id = 'HDA NVidia'
  alsa.card_id = 'HDA NVidia'
  alsa.card_id = 'HDA NVidia'
  alsa.card_id = 'HDA NVidia'
  alsa.card_id = 'HDA NVidia'
  info.product = 'HDA NVidia ALSA hardware specific Device'
  alsa.card_id = 'HDA NVidia'
  info.product = 'HDA NVidia ALSA Control Device'
  alsa.card_id = 'HDA NVidia'
  info.product = 'HDA NVidia Sound Card'
  sound.card_id = 'HDA NVidia'
  info.linux.driver = 'HDA Intel'
    22:     489835        578   IO-APIC-fasteoi   sata_nv, HDA Intel
       HDA Intel: /devices/pci0000:00/0000:00:0e.1
       HDA Intel: module = snd_hda_intel
irq:0 22 (   490413) "sata_nv" "HDA Intel"
       HDA Intel: /devices/pci0000:00/0000:00:0e.1
       HDA Intel: module = snd_hda_intel
       HDA Intel: /devices/pci0000:00/0000:00:0e.1
       HDA Intel: module = snd_hda_intel
  E: DRIVER=HDA Intel
  <6>HDA Intel 0000:00:0e.1: PCI INT B -> Link[AAZA] -> GSI 22 (level,
low) -> IRQ 22
  <7>HDA Intel 0000:00:0e.1: setting latency timer to 64
  Driver: "HDA Intel"

Sid.
