The PREEMPT_RT patches for kernel 2.6.26 are still under development. Please post the various kernel messages you are observing. BTW: The most recent 2.6.26 patch is 2.6.26.6-rt11. > My questions are: How can I have more details on the tests which > where used to evaluate the platform running the config_preempt_RT > (specifically on networking issues)?

For the time being, linux-2.6.24.7-rt21 is believed to be stable and ready for production. This version has been tested heavily under x86 (slow/fast machines, single/dual/quad core, 32/64 bit) and under various PPC platforms. It has been tested less heavily on ARMs and MIPSes. There are no known issues on x86 platforms. Would you mind to run 2.6.24.7-rt21 on your machines?
