Hello I'm back after some testing.... and it is a complete mess; actually there is more than that just problems with linuxsampler.... with every RT kernel greater than 2.6.31.12 (i started seeing it on gentoo), i have total system freeze... after a few minutes.... to the point that i have to force shut down the system without proper shutdown (i hate doing that); i have installed "das-watchdog" and see the pop-up window saying that das watchdog has disabled real-time for 8 seconds... and this pop-up appears every 8 sec... (forever)... everything happen before i have time to play a single note.... This old problem is coming again... and i've open a new subject to solve this first Vic > Date: Mon, 31 Jan 2011 13:17:49 -0200 > From: lclaudio@xxxxxxxx > To: nadaeck@xxxxxxxxxxx > CC: linux-rt-users@xxxxxxxxxxxxxxx > Subject: Re: disk thread problem when using RT-kernel > > On Mon, Jan 31, 2011 at 03:16:37PM +0100, Victor henri wrote: > | > | Hello Daniel and Luis > | > | - Yes i'm using the rtirq script; > | > | - I'm using the latest version of linuxsampler 1.0.0 (in Gentoo : from > | pro-audio overlay; in Ubuntu : not in the repositories so I compile it > | myself, after taking it on the linuxsampler website); same for libgig > | (dependency of linuxsampler); > > Have you tried running linuxsample at a higher priority?
