via82xx & acpi -> freeze bug

[Pavel Kysilka]

	Hi all,

i have via82xx based onboard soundcard.
i test toady new kernel 2.6.1-rc2 with suspend to disk (echo 4 > sleep).
my computer totally freeze with loaded module snd-via82xxx. if this
module not loaded, suspend to disk working with no problem.
kernel 2.6.10-rc1 working with this feature ok.

i rewrite by hand this lines (no information in log).

It sounds like the via82xx suspend/resume support may not be
implemented.  You should file a bug report:

https://bugtrack.alsa-project.org/

Unfortunately the bug tracker is down right now...

I assume you are talking about suspend/resume support for the emu10k1
driver.  I might implement this.  However it is not very high priority.
See the emu10k1 /proc thread from yesterday for an explanation of what
needs to be done.

It is implemented.  Pavel wrote the it worked with 2.6.10-rc1.

I guess this is because of the change of the kernel PCI core, removal
of pci_save_state() in the core driver.  This was already fixed in the
ALSA CVS.  Give it a try.
