Sigh, I'm not that good at all. I spent two weeks on and off on that for nothing, at least on my builds MIDI is still not working for 2.6.26.x rt (your suggestion - thanks! - enabled midi input to work but there was not followup and something is still drastically wrong with the alsa timer - apps that use it don't actually output anything). I meant to post it but this last couple of weeks I had other priorities and posts like "midi does not work" or "it freezes" without hard data will probably not help either. ... and the last few times I have posted with problems I have not received any feedback from lkml except for you. And no forthcoming patches to test or anything like that (with one exception for some BUG reports but that lead nowhere). At least from the point of view of my email account I get a lot of silence. Maybe I'm not being cc'ed? I just can't at this point try to follow lkml directly (I did till the beginning of this year). > The RT kernel work lately has been driven by > traditional hard RT users like simulation, machine control, HPC, etc > who all seem to be happy. Strange. Maybe different configurations or hardware? When I try to run 2.6.26.x rt patched kernels I eventually end with a completely dead machine, not very often (once every two days?) but it happens (I don't currently have a way to trace what happens). And there's nothing official AFAIK for 2.6.27.x. > Also the kernel RT people are focused on > getting the RT kernel patches into mainline. That would be sooooo good.... at least then it would _have_ to keep up with new releases. At this point I'm also ready to give up and just try to find latency problems in the vanilla kernel, find a way to trace their origins and report that to lkml. -- Fernando _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
