Hi Marco,

I recompiled a real time kernel for 13.04 following the system
configuration guide (in this case the italian translation that reports
"3.2.35-rt52").
http://linuxaudio.it/index.php/Configurazione_di_sistemi_audio_GNU/Linux#Compilare_il_tuo_real-time_kernel

I'm using an hp pavilion 6 laptop with the ua-25 ex soundcard and with
this particular real time Kernel everything works fine.
1 xrun discovered at 5,8 ms latency in 3 hours session, recording and
mixing with Ardour.

Best regards
Nicola
