[LAU] no midi with 2.6.26 or 2.6.27

[Tony Smolar]

Hi-

Yes, there is apparently a very similar issue in the RT kernels.  I even 
go ahold of the patch and attempted to fix the issue in the latest  
kernel I compiled,  only to find that particular bug did not exist in my 
version of the source.    I contacted the maintainer, and he said the 
fix was for the RT kernels, since that bug in question only existed there.

Anyway, to make a long story short, whatever ails my kernel is a 
completely different bug with the same symptoms :-(

Thanks for the response.   I suppose I could try downgrading kernels to 
see if I can find a fix that way.
