Hi, we have a well running X86 Realtime system with Kernel 2.6.29 and xenomai-2.4.10. The system is able to boot from a stick and runs on all our computers. To fix some X11- problems with newer graphic chipsets, we try to upgrade to a newer Kernel version.
We are starting with Kernel 2.6.34.5 and xenomai-2.5.5.2 using the latest ADEOS-patches. 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. All permutations of Kernel 2.6.34.5, Kernel 2.6.35.13, xenomai-2.5.3, xenomai-2.5.5.2, xenomai-2.5.6 has the same problems on the Core 2 Duo 3 GHz machines. On other machines with slower Mobile Core 2 Duo or Pentiom M processors the system runs or has sometimes the same problem. I have try some changes in the Kernel configuration, without any success. 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. Thanks in advance Mit freundlichen Grüßen / Best Regards Bernd Benner MH/SGT3 moehwald Bosch Group Moehwald GmbH Michelinstraße 21 66424 Homburg GERMANY www.moehwald.de [email protected]<mailto:[email protected]> Moehwald GmbH, Sitz/Registered Office: Homburg/Saar, Zentrales Handelsregister/Registered Court: Saarbrücken HRB 2812 Geschäftsführung/Managing Directors: Jens Last, Wolfgang Geenen
