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
