S1 could work

S1 could work

[Tod Morrison]

Hopefully this is can be done. I have partially functional S1 and S3 
states, in the case of S3 the LCD remains off after resume which I gather 
may be a problem for awhile, but I'm patient. The problem with S1 is just 
frustrating though, I have no way of powering of (i.e. dpms) from the 
console (setterm doesn't work) and S1 doesn't turn off the LCD. This 
wasn't a problem under 2.4 since I would just execute 'xset dpms force 
off' from within X before suspending. Unfortunately, in 2.6 acpi switches 
to a text console to display some messages prior to going into standby 
which breaks my only work around. I'd like to know if there's anyway 
around this, as it essentially makes 2.6 kernels unusable to me.

Switching consoles doing S1 is not neccessary on working hardware. You
might want to simply comment it out.

Can you give me a pointer where switching is done? I could not find it.

Trying to enter S1 when pdnsd is running aborts standby. But pdnsd is
killed by entering S1 or S3 (didn't know S4 because it didn't work for
me). Entering S3 with a running pdnsd works.

By entering S1 audio from my tv-card will not stopped.

Resuming from S3 will only work if i unload all sound modules. But i'm
not able to reload them successfully:
Starting ALSA (version 1.0.1):AC'97 0 does not respond - RESET
AC'97 0 access is not valid [0xffffffff], removing mixer.
EMU10K1_Audigy: probe of 0000:00:0d.0 failed with error -5
 emu10k1 bt87x.
Restoring ALSA mixer settings ... done.

Without sound module unloading there is:
Kernel panic: Fatal exception in interrupt

Best regards,

kernel/power/console.c

And do you want it to stop?

If so add suspend/resume support for your tv-card.

...suspend/resume support is clearly needed for your sound card.
