RE: problem of disk threads whith every rt kernel, except with kernel-2.6.31.11!
Yes i forgot to mention that is the RT kernel that makes the difference; for now, it works ok with the generic kernel with optimized parameters, such as - preemptible kernel (low latency desktop); - timer frequency 1000 Hz but it works quite ok with Linuxsampler alone; but when i want to add some applications, for example rosegarden to record, Xruns arrive, even with a bigger latency in jack > Date: Sat, 29 Jan 2011 22:02:34 + > Subject: Re: problem of disk threads whith every rt kernel, except with > kernel-2.6.31.11! > From: ricardolame...@gmail.com > To: ubuntu-studio-users@lists.ubuntu.com > > Have you tried it without RT kernel? > > > 2011/1/29 Victor henri > > (I've posted this already without subject; i allow myself to repost to > make it; please ignore the other one; i apologize for the mistake i > made) > > Hello: > > I have a problem since almost one year now.

problem of disk threads whith every rt kernel, except with kernel-2.6.31.11!
(I've posted this already without subject; i allow myself to repost to make it; please ignore the other one; i apologize for the mistake i made) Hello: I have a problem since almost one year now. I'm using linuxsampler, that allows that load very big sample files (one of my .gig file is 1.6 G for only one piano sound); this use disk streaming. I always have such problem only when i use the RT kernel : 0x7f6eef1ee860 Disk stream not available in time! After several message slike that, i get : DiskThread: there was no free slot Disk stream order failed! Then the sounds clicks, then stops for 10 to 20 seconds, then i can play again, then it'll come again... This arrives on both Gentoo and Ubuntu 10.10 64 bits; BUT there is one thing however : there is ONE kernel with wich it doesn't arrive : the 2.6.31.11-rt from Ubuntu lucid (RT kernel was in the repositories in Ubuntu untill 10.04 Lucid, then now i have to either take it from Abogani's ppa (for lucid or natty) or compile it myself with the rt-patch from kernel.org; i've tried all of that, and nothings works, except for the 2.6.31.11-rt from in the repositories of Ubuntu Lucid-updates) Here are some technical details: - I have laptop Asus Core i7 for gamers (supposed to be very fast);to be noted : it also happens on another Asus Core I7, but NOT on an another Asus Core i3; 4Go RAM; - when i compile myself i choose : real-time preemption (of course) and Timer frequency 1000 Hz, either on Gentoo or on Ubuntu with kernel from kernel.org; nothing else is changed in Ubuntu. - i've tried with the no-op cfq scheduler also; i use ext3 on Gentoo and ext4 on Ubuntu; - have a nvidia graphic card, but no proprietary driver installed i have posted that at the linuxsampler mailing list without succes Could please someone help me? i LOVE RT-kernel and its capabilities What is it in the linux-rt package that is not somewhere else and that allows things to work for me?
