Dell Vostro 1520: hda wrong initialization in APIC mode

[Yuri Dario]

When ACPI 3.18 boots in /SMP /PIC mode, the HDA multimedia hardware is correctly initialized; when /APIC mode is used, the device is incorrectly activated and uniaud fails to load.

I'm attaching pci dumps in both situations. Looking at file diff, shows that PIC mode initializes memory address as

  PCI Class Multimedia, type Unknown!
  Subsystem ID 02BC1028h Optiplex 755 (Guess Only!)
  Subsystem Vendor 1028h Dell
  Address 0 is a Memory Address (64-bit) : F6500000h..F6503FFFh
  System IRQ 5, INT# A

while in APIC mode

  PCI Class Multimedia, type Unknown!
  Subsystem ID 02BC1028h Optiplex 755 (Guess Only!)
  Subsystem Vendor 1028h Dell
  Address 0 is a Memory Address (64-bit) : F6500000h
  System IRQ 22, INT# A

Also Ubuntu uses first configuration. Talking with David, he says that device got wrong initialization from acpi, so uniaud fails to load.

Sorry for late reply, just discovered I don't get email updates about tickets.

Tried 20-04-11 version, does not boot at all in APIC mode, it hangs on some driver.

Works as before in PIC mode.

I tried the latest build, Acpi319APICFIX2-20110611.zip, and while it boots fine in PIC mode, in APIC mode it hangs solid at os2 boot logo.

This is even worse than previous builds, at least before I was able to perform most boot sequence before hanging...

Fixed in David's ACPI builds.
