Thanks for the tip, I search for this option and seems to relate to nvidia

The problem is related to the APIC timer interrupt, the CPU goes into enhanced
halt state (C1E) but is not able to wake up. See AMD erratum #400 and what
acpi_skip_timer_override actually does. See also
/arch/x86/kernel/process.c.
My personally advice is that you don't use C1E at all, but if you like
to, acpi_skip_timer_override will most probably fix it for you.
Have you tried?
Yes, I have tried and it does work.
So, this is a processor bug? I would expect that Linux should detect
these automatically...
So, my AMD 920 cpu is not only slow, it has also some errata
incompatible with Fedora. Nice :D
Thank you for pointing to acpi_skip_timer_override option...
