Hello,

I outline my problem:

I = tried to install Linux on my new dual-processor system:
Ubuntu 10.04, Ke= rnel 2.6.37.6
Adeos 2.6.37.6
Xenomai 2.5.6

My board has two pr= ocessors with 6 cores per processor.

I boot my patched system. Linux= starts and after a few seconds the system freezes. And I get the following= message over my serial debugging pc:
