Hello everyone. I decided to upgrade to a 2.6.11 kernel following the advices Maarten de Boer and Pau Arumi who gave a nice presentation at AES 2005. I was previously running a 2.6.8 kernel and everything was fine with my Asus L2000D laptop (SiS soundchip onboard running Trident4D ALSA driver, Evolution UC33 MIDI controller up and running). The only lack was realtime audio. I never dared taking the first step into realtime kernel tuning. I upgraded to the 2.6.11 using make oldconfig and tuning it for realtime (Security options and other stuff). Compilation went right. I compiled Pd again and when I tried starting it it froze the whole system: no mouse nor keyboard control, no X response (no graphical refresh)... I recompiled the kernel 3 or 4 times changing a few options, recompiled Pd as well. Nothing changes: complete system freeze. I'm running a Debian unstable, Fluxbox desktop. Anyone got a clue on what's wrong? Alternatively, what benefits will I really earn upgrading from 2.6.8 to 2.6.11? Maybe I can tune my good old 2.6.8 to do realtime as good as a 2.6.11? Cheers list.
