SB600 sound module disabled on kexec

[Loïc Grenié]

    Hi,

    I have had this problem for a long time and not reported
  it earlier. Sorry. This might have been true already for
  2.6.18...

    I have a laptop with an ATI (AMD) SB600 south bridge
  including a sound module. When I boot the kernel from the
  bootloader, there is no problem: hda-intel drives the module.
  When I kexec the kernel, there is a problem with IRQ
  configuration and the sound is disabled.

    I have attached lspci.[01], dmesg.[01] and config. The
  suffix is .0 for a bootloader-booted kernel and a .1 for a
  kexec'ed kernel.
  Full disclosure: I've swapped some lines (but not
  modified any) in the dmesg.[01] to reduce the number of
  differences between the files. I think it should not matter
  (the error does not seem to be related to the order of the
  initialization of the various subsytems), but if it does please
  tell me.

   Thanks,

    Loïc
