I'm using Xenomai for scientific data acquisition, so I'm quite
interested to the issue. Can I ask you to detail how you solved the issue?

Maybe it's not much related, but there is any possibility to synchronize
either linux or xenomay clocks to an external clock source, let say the
GPS timing signal from a GPS receiver?

Thanks. Cheers,
