Thanks, Arnold, for the heads-up on this particular kernel. I found it

to hang on two occasions (and I haven't had it for that long either).

I'm not too familiar with PPAs... (am reading up right now). I assume

you meant that I should follow the instructions on this page:

https://launchpad.net/~ubuntustudio-dev/+archive/ppa

and then choose the right realtime kernel package from synaptic, or

command line. Am I correct?
Jörn, my apologies,  I realised that I haven't answered all your

questions - my frames/period is 256, periods/buffer is 2,  sample rate

is 44100, giving me a latency of 11.6 sec. While typing this, I noticed

a parameter 'Timeout', which is currently 500 msec. The only "error"

message says something about timeout and linuxsampler - so I was

wondering whether I can change this parameter to a 'safer' level. What

does this 'timeout' parameter mean? The qjackctl popup says "Set client

timeout in milliseconds", but I didn't quite follow. What happens if

this parameter is too high, or too low?
Also, I've noticed that the realtime kernel + Icewm option *does* reduce

the crash frequency by a huge margin, something which I did not make

clear in my last mail. However, the realtime kernel hung twice on one

occasion (before a live perfomance), forcing me to switch to the generic

kernel, and the crash happened during the performance (does not help

increase my fanbase.. :(). On the whole, I cannot confidently rely on

the linux setup until there is some failsafe in place, and I'm convinced

that it is very, very unlikely for a crash to happen during a live

performance.

Looking forward to suggestions/pointers/questions.

Thanks in advance!

Cheers,
Guru
