[Xenomai-help] xeno-test failed to start in-kernel timer benchmark, code -25

[Hugo Braga]

I ran xeno-test and I got the following failed message:

Seg Nov  5 10:30:38 BRT 2007
running: ./run -- -sh -T 120 -t1 # latency
*
*
* Type ^C to stop this application
*
*
== Sampling period: 100 us
== Test mode: in-kernel periodic task
== All results in microseconds
latency: failed to start in-kernel timer benchmark, code -25

I enabled the following options as module in the kernel's configuration
file:
Real-time sub-system->Drivers->Testing drivers:
*Timer benchmark driver
* IRQ benchmark driver
* Context switch unit testing driver

Also the system stopped when this message has been shown and I had to reboot
the machine.
My machine is:
Intel Core 2 Duo 2.00GHz
Intel Deskop Board D946GZIS
I built linux 2.6.19.7 linux kernel with xenomai 2.3.4 and
adeos-ipipe-2.6.19-i386-1.7-03.patch. I unchecked CPU frequency scaling,
unchecked ACPI->Processor and unchecked APM.
Please help me to solve the issue.

Thanks,
Hugo

Before starting the test, make sure that the xeno_irqbench module is not
loaded (there are other workaround for this issue, but this one should
be the simplest). One day I really need to fix this, I'm afraid...

No problem at all, your English is fine!
