I'm pretty sure this wasn't a "regression" and was always there, and
that the proposed patch did fix the solution, right Paulo and Alan?

I'm also pretty sure that it's not a regression and that the patch 
should have fixed it.  But since Paolo hasn't replied to any of our 
queries, we can't be certain.

holiday's and work's with linux well. I'am beginer in linux and I can't put 
the patch to work, because of that I'am waiting for him to see if the patch

Regards, Paulo.

Ok, it's queued up for after 2.6.22 is out as it is not a regression and
is kind of intrusive.

Unless others think it should go in now?
