Ok, it's there also in 5.11.2:
[ 0.000000] rcu: RCU calculated value of scheduler-enlistment delay is 25
jiffies.
[ 0.000000] NR_IRQS: 128
[ 0.000003] sched_clock: 64 bits at 1000MHz, resolution 1ns, wraps every
4398046511103ns
[ 0.106687] WARNING: timekeeping: Cycle offset (26) is larger than allowed
by the 'jiffies' clock's max_cycles value (10): time overflow danger
[ 0.106698] timekeeping: Your kernel is sick, but tries to cope by
capping time updates
