Fedora sees only 1 CPU core after updating the kernel to 6.9.x

Tried, but no luck.

Meanwhile…

I hate to restart it now, but I’ll try it in a few days.

And from the above topic, the bug report URL: 2295026 – 6.8 kernel see all cpus, 6.9 only sees 1 cpu

Probably late update, but just in case.
Kernel 6.9.2.x sees all CPU cores too.
