There should be some other messages around that. Could you please attach a full dmesg from boot?
Created attachment 675949 [details] dmesg
Please see it above. Thanks.
TSCs are kind of notorious for going out of sync between CPUs. This is just saying the kernel isn't going to use the TSC. Later in the boot, it switches the clocksource to hpet, so things should be fine. There's really nothing to fix here.
