No, I did that configuring many moons ago.

Yes I do, and it doesn't mean PREEMPT_LAZY, which is what you said
you were going to configure.  Since you didn't post the output
of uname -a, I suspect you didn't do what you said you were
going to do.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/kernel/Kconfig.preempt?h=v6.13

config PREEMPT
        bool "Preemptible Kernel (Low-Latency Desktop)"
[...]
          This option reduces the latency of the kernel by making
          all kernel code (that is not executing in a critical section)
          preemptible.  This allows reaction to interactive events by
          permitting a low priority process to be preempted involuntarily
          even if it is in kernel mode executing a system call and would
          otherwise not be about to reach a natural preemption point.
          This allows applications to run more 'smoothly' even when the
          system is under load, at the cost of slightly lower throughput
          and a slight runtime overhead to kernel code.

          Select this if you are building a kernel for a desktop or
          embedded system with latency requirements in the milliseconds
          range.
[...]

And not only that, but you're running the Pan of our forefathers...
