Good news, thank you.
I did try the 6.11 with RT on this PC and it failed to load, need more time to test on more hardware, soon!

You still need to set the PREEMPT_RT flag and build the Linux kernel. its not RT by default.Linux is now RTOS. It took 20 years but they finally succeeded !

6.11 shows SMP PREEMPT_DYNAMIC out of the box, did not test LinuxCNC yet.

PREEMPT_RT Real time OS is supported natively from Kernel 6.12 and on so not 6.11 (which will require applying the RT patches) before setting the Preempt RT switch and building.6.11 shows SMP PREEMPT_DYNAMIC out of the box, did not test LinuxCNC yet.
