bytes_to_frames() divides by runtime->frame_bits which is not set until
after the hw_params callback has succeeded, but the corresponding
chip->substream[] entry is set in that callback, by init_engine().  It
should probably have been set in the prepare callback.

Frederick, please try the patch below.

Takashi, is there any reason why the runtime-> fields are initialized
after the hw_params callback?

How can an irq arrive before hw_params() and prepare() ?

Frederick, are you using the midi interface ?

I've just had another look at my code. Although it never happened to me, it
is indeed possible when hw_params() completes if another substream is
already running. The reason is that the card delivers an irq when it
executes an irq instruction in any of the running s-g lists. The irq
handler cannot know which substream caused it, so it has to call the
pointer() function for each of the configured substreams (ie. the ones
which completed one of the pcm_*_hw_params() callbacks.

There is another possible fix. I tested it briefly. It looks ok wrt race
conditions because pipe->state is set only in the trigger callback. I hope
I didn't overlook anything again...

I've tried some newer kernels.  Still having problems with the echo 3G.  
This is kernel version:
2.6.32.13.  The above patches posted to the linux kernel list seemed to 
get rid of the crashes, but evidently did not go into the main kernel tree.
Any help appreciated.  I am willing to help to the best of my ability. 
Thanks!

Indeed. I've just checked 2.6.33 and the patch isn't there. It's in 2.6.34.

If you need 2.6.32.13 you can apply the above patch to the kernel tree or
download ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.23.tar.bz2,
otherwise just use the latest kernel.

Care to send the patch to stable kernel (with the upstream commit id)?

I tried 2.6.34.   I have jack 1.9..5 installed.  I was able to use 
rhythmbox to play mp3s.  I could not use the echomixer app.  It complained
about a channels mismatch.

My goal is to be able to plug in a MIDI keyboard, or USB guitar 
interface and play along with songs etc.

I plugged in a MIDI keyboard, "/proc/asound/cards" showed the keyboard 
was recognized.  The keyboard has a USB and MIDI interface.
I am not sure if they both work at the same time.  I had the MIDI cable 
plugged into the Gina3G, but I could not tell if the keyboard was 
recognized.
I compiled csound5.  When I engaged it the system immediately froze and 
started spitting out:

I'm running 2.6.34 now. Both a very old version of echomixer (2005!) and
the latest version I just compiled from alsa-tools-1.0.23 work fine with my
Gina3G. Please quote the error message.

Ok, I compiled csound, but I don't know how to use it. How can I reproduce
the problem ?

Sorry I took so long to get back to you.
It turns out Csound is not related to the problem.

In this case I am only using kernel 2.6.33.5-rt23-amd64, alsa lib 1.0.2, 
but 2.6.34 does it too.
I bring up firefox.  Web pages attempt to play sound.   The kernel 
begans doing:

[ 2879.766331] allocate_pipes: ch=1 int=2
[ 2879.766332] allocate_pipes: channel already open
[ 2879.766333] allocate_pipes(1) err=-11
[ 2879.766334] pcm_hw_freed
[ 2.821190] pcm_analog_out_open  cs=0  oc=2  r=44100
[ 2879.821266] allocate_pipes: ch=1 int=2
[ 2879.821267] allocate_pipes: channel already open

,infinitely.  The system is unusable at this point and I have to 
Alt-SysRq-k to get back in.

Let me know what other information to provide.

Perhaps is it related with the OSS emulation ?  Do you know if the browser
plays the sound itself or if it is using an external program or plugin ?
