Hi,
I won't write too much, the following session will tell much more:

I know this is a FAQ when CPU frequency throttling is used, but this is
not the case here. I killed powerd(8) and dev.cpu.0.freq is set to its
highest frequency (1733).
IOW, using ACPI-fast as timecounter leads to have "sleep 1" actually
sleep for 6~7 seconds. Using TSC as timecounter is even weirder since it
desynchronize the computer's clock.
I attached the dmesg of my computer, and can provide verbose dmesg if
need, or anything else requested to help debugging.
Thank you.
Regards,
