I just found some fix with changing clock source :
from
cat /sys/devices/system/clocksource/clocksource0/current_clocksource
tsc
into
bash -c 'echo hpet > /sys/devices/system/clocksource/clocksource0/current_clocksource'
but I am first time in my life troubling this issue anyone knows what was wrong here ?
