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.

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?

	Carsten.
