serial synth with kernel 2.6.35.2

serial synth with kernel 2.6.35.2

[Chuck Hallenbeck]

Hi,

Using Arch Linux, I just upgraded my system to kernel 2.6.35.2, with no
observable problems so far. In particular, my doubletalk lt continues
to work fine on serial port ttyS0.

I haven't upgraded the kernel on my system yet but I tried your
suggestions for the Speakout and no go.  I got nothing!  In the
meantime, I'm going to explore creating a serial module for Speech
Dispatcher; there may be some interest there for those who might wanna
use a serial synth on their systems with gnome and other subsystems
that rely on Speech Dispatcher.

I think my last message on the other serial thread included some
errors I got while trying to load the spkout module.

Hi Steve,

I recall your earlier posts, and evidently the experts are just as
puzzled as we followers are. There doesn't appear to be a clear pattern
of which configurations fail and which work okay. I just thought I'd
add one more fact to the available data on what works and what doesn't.

OK, I tried again with my 2.6.35.2 kernel on ArchLinux but as
expected, no go <sigh>.

However, This time, I captured some noise from dmesg, thinking that
might show some more hints to who so ever may have a greater knollege
of kernel internals.  I loaded speakup_spkout with the start=0 option
and the load was successful with a return code of 0; but when I used
talkwith to specify spkout as the synth, I got the following messages
in the dmesg listing.

releasing synth soft
unregistered /dev/softsynth
synth probe
Ports not available, trying to steal them
Trying to free nonexistent resource <00000000000003f8-00000000000003ff>
Speakout: not found
spkout: device probe failed
failed to init synth spkout

After that, I went and reloaded softsynth and that part was fine
again.  I can still echo messages to /dev/ttyS0 and speakout talks
that stuff with no problem so the port is actually working and all
that.

Could you post the content of your /proc/ioports with that kernel?

Try commenting out the return (NULL); line after the unable to allocate port 
warning. You might be arested by the kernel police so be careful!!!
