* ALSA, snd_intel8x0m and kexec() don't work together (2.6.13-rc3-git4 and 2.6.13-rc3-git3)

Whenever I use kexec() to reboot into a new kernel, sound doesn't work
properly. KDE doesn't display a mixer.
All modules seem to be loaded, though - and after a reboot using
"reboot" instead of "kexec", sound works flawlessly with the same setup.
/etc/init.d/alsa restart doesn't change things, either.
The one message strinking me as odd during the boot-process is:

Dunno what to do next. Shots in the dark:
Did it wok with 2.6.12 for you?
Maybe start adding printks in snd_intel8x0_create(),
where snd_intel8x0_chip_init() is eventually called.
You want to find out what is the difference in hw behaviour
bebween good and bad boot.
Maybe do a superfluous pci_disable_device/pci_enable_device pair there.

2.6.12 didn't have kexec (unless it's a -mm kernel)
So how could you boot using kexec then?

I can try that.

Is kexec supposed to be transparent to all the subsystems, or does ALSA
have to know how to stop all DMA in order for kexec to work?

The way I used it was to replace the "reboot" call in
/etc/init.d/reboot. So at that time, ALSA was already "stopped"
(/etc/init.d/also stop ran) -- shouldn't that suffice?
Kconfig says:
kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot but it
is indepedent of the system firmware. And like a reboot you can start
any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.
It is an ongoing process to be certain the hardware in a machine is
properly shutdown, so do not be surprised if this code does not initially
work for you. It may help to enable device hotplugging support. As of
this writing the exact hardware interface is strongly in flux, so no good
recommendation can be made.

It is fairly transparent. device_shutdown on reboot should stop
DMA but that is not kexec specific. kexec may be the only way
the code path is easily tested.
The basic requirement from the kexec side is that the drivers
be able to bring back the device from the state they left it
on reboot.
So in essence it is transparent. But if your driver is not
robust you can have problems.
The fact the new kernel was coming up indicates that kexec
worked but the driver did not successfully initialize,
the hardware from the state it placed it in during shutdown.

Hmm. It looks like the text in Kconfig needs to be updated.
I don't think that description has been updated in several years.
