Re: [LAU] no midi with 2.6.26 or 2.6.27

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.
