2010-07-07 15:14:18     xenomai kernel panic

Shawn Morgan (UNITED STATES)

Message: 91010   

I'm trying to add xenomai support to the uClinux kernel. I've enabled the xenomai package (2.4.0) that is included in the 2008R1.5-RC3 distribution. When I download the kernel to my device and try to run the latency benchmark app the kernel panics.  Any help would be appreciated.
