yes, I made sure to start on the realtime kernel (I have to choose it
manually in grub) and I have done some stuff from here as well:
http://wiki.bxlug.be/ProjetAudio/KernelRealtime
(frenchio!)

this grep gives me this:
:~$ grep -i PREEMPT /boot/config-`uname -r`
# CONFIG_DEBUG_PREEMPT is not set
CONFIG_PREEMPT=y
# CONFIG_PREEMPT_DESKTOP is not set
CONFIG_PREEMPT_HARDIRQS=y
# CONFIG_PREEMPT_NONE is not set
CONFIG_PREEMPT_NOTIFIERS=y
CONFIG_PREEMPT_RCU=y
CONFIG_PREEMPT_RCU_BOOST=y
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT_SOFTIRQS=y
# CONFIG_PREEMPT_TRACE is not set
# CONFIG_PREEMPT_TRACER is not set
# CONFIG_PREEMPT_VOLUNTARY is not set


So I'm running 2.6.28-3-rt on Ubuntu 9.04 jaunty

What's the diagnosis doctors ardour?

thanks
