I made a change to the MIDI initalization code about one year ago, in
ALSA 1.0.5.

This is the same old well-known bug -- for some reason, the MIDI
interrupt isn't enabled.

I think it may be possible to change the driver to use polling
instead.

Hi,

we probably used this patch for the c-port midi prob.
but we have no idea how to get this patch into our 
2.6.11.7 kernel - all files are ending with .v, but the .v must be away for 
overwriting the old files....

Tried it with 1.0.9rc2.
No luck unfortunately.
