Hi Alessio,
great that you want to manage these kernels!

I'm mostly curious about -lowlatency, but unfortunately I haven't got 
around to test it. I think -preempt is a server kernel? Could you also 
say that -lowlatency is the desktop version of -preempt?

Is there a difference between -rt and -realtime, except that your 
-realtime seems more updated than -rt? Do you think we should replace 
the official linux-rt, with your linux-realtime?

(I read your post on but 
couldn't find the answer to those two questions there.)

Currently I use the generic kernel.

First I think I need to educate myself and get some hands-on experience 
of the lowlatency kernel. I need to understand when you should use one 
kernel or another.

I've been working with audio issues, and since two months back I'm a 
part of the Ubuntu/Canonical kernel team. (I e quirking HDA hardware ;-) )
I'm a little new in this land, and haven't followed kernel development 
closely until now, so I'd also like to ask you - do you feel you have 
the support you need from the kernel-team's side for maintaining these

I think we need to have it for every release, to get the best possible 
testing and quality of these kernels. If that's possible?

Just to clarify, did you mean "if you need help" (you help me) or "if 
you want to help" (I help you) ?
