Re: [Xenomai-help] rt_task crash kernel

Ok, some messages occur on the console with latency.

For information I have successfully installed and used Xenomai 2.3.1 with
2.6.15 kernel on the same board.

You can do something like:

static int ticks;

if (!(++ticks % 1000))
    printk("%d ticks\n", ticks);

Which will only print something once every 1000 ticks.
