Hi again,

i did some other playing around this evening. (Debugging would be a word 
much too big...)

I commented out the logic stuff in the following subroutines of the 
ice1724.c:

- static int vt1724_midi_output_open(struct snd_rawmidi_substream *s)
- static int vt1724_midi_output_close(struct snd_rawmidi_substream *s)
- static void vt1724_midi_output_trigger(struct snd_rawmidi_substream 
*s, int up)
- static void vt1724_midi_output_drain(struct snd_rawmidi_substream *s)

The vt1724_enable_midi_irq(s, VT1724_IRQ_MPU_TX, 1) is killing my 
kernel, i don't know why.
On the input side everything works, so i am a bit confused. Again. ;-)

I will continue debugging, at all this seems to be a good starting point 
for me.

It would be glad, if you could help me some way.

Martin
