Reused the same kernel sources, choosing "Pentium-classic" M586TSC and no more activated "math emulation". And surprise it works perfectly ! So for me, it's seems not to be really the same processor, and not only a FPU add-on difference... Even if when I asked ICOP, they tell me only performance & FPU difference, strange. Interesting, this time here what cat /proc/cpuinfo gives me : processor : 0 vendor_id : Vortex86 SoC cpu family : 5 model : 2 model name : 05/02 stepping : 2 cpu MHz : 799.974 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc cx8 bogomips : 1599.94 clflush size : 32 cache_alignment : 32 address sizes : 32 bits physical, 32 bits virtual power management: For information, Xenomai has been configured like that : ./configure --disable-x86-sep CFLAGS="-march=i586 -fno-omit-frame-pointer" LDFLAGS="-march=i586" (I was surprised that the -fno-omit-frame-pointer were again necessary!!!) With latency -p 10000 with load, best = 19 micro-secs & worst = 63 micro-secs. The price is quite less for the vsx version, and even if also less efficient for real-time, for my application it should be yet enough (2-3 tasks at 5-10 milli-secs) !? (With VSX version, worst latency gives 200 micro-secs... finally not so much ?) And lastly, dmesg for people that could be interested with: [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 2.6.38.8-xeno_mld (marc@marc-laptop-airis) (gcc ver sion 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) ) #10 Mon Jul 9 14:29:52 CEST 2012 [ 0.000000] CPU: vendor_id 'Vortex86 SoC' unknown, using generic init.
