es1968 suspend2ram problem

Hi there

I got suspend2ram working on my desktop machine, using a terratec dmx (quite old, but rock-solid hardware mixing) with
es1878 Chipset.

If I'm unloading the module before hibernation and reload after wakeup everything works (thought kmix and kradio are
being closed, which is a bit stupid). If I'm trying to suspend with the module loaded no sound output is possible after
wakeup (mixer still there). An alsasound restart won't bring the soundcard up again (no mixer, no nothing).

Tried this with kernel 2.6.22 buildin alsa as well as the freshest HG tree.
System is Gentoo.

Any ideas where to search for that problem? Looks like a bug to me.

Christian

Try newer version of kernel.  There were some bugs regarding
hibernation with 2.6.22 kernel, which were apparently fixed on 2.6.23
and later.

running 2.6.24 now, nothing changed, has anybody had success with es1968 and suspend2ram?

Ah, I overlooked that you are handling S2RAM.  OK, then it's slightly
different from hibernation.

Though, S2RAM has no difference in the sound driver code from
hibernation.  So, if S2RAM doesn't work but the hibernation works,
it's often rather a problem in the PM core part.  I'd check whether
the hibernation works or not, at first.

The hibernation with es1968 chip worked fine on my old laptop, AFAIK.
