This system works on some test machines, but on some Core 2 Duo 3 GHz systems with Intel Desktop Chipset ( Lenovo and HP ) the system freeze and/or produces strange console outputs ( only line feeds ) after a start of latency or clocktest. > We are not able to get a kernel log from this systems.

I have also try a combination of Kernel 2.6.35.13. and xenomai-2.4.10 with some changes in the xenomai headers to run with newer Kernels. This version has the same problem on the Core 2 Duo 3 GHz systems. > > Is there any way to find the reason of this problems with Xenomai 2.5.X and newer Kernels 2.6.3X with 32 bit X86 or has anybody similar problems fixed. The latest x86 fix can be found in git: http://git.denx.de/?p=ipipe-2.6.git;a=shortlog;h=refs/heads/ipipe-2.6.37-x86 ie. ipipe-2.6.37-x86 branch of git://git.denx.de/ipipe-2.6.git It's surely worth retrying with that version and latest Xenomai (maybe even 2.6.x git, though 2.5.x should contain all known fixes). Otherwise, please provide your .config. Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
