In summary: - OpenBSD 7.2 amd64 kernel TSC and lapic calibration is broken on (at least) some ESXi 6.0 and ESXi 7.5 hosts under the VM configuration "FreeBSD (32-bit)". The ACPI PM timer seemingly accelerates when we read it repeatedly during boot. - Workaround 1 is to change the configuration to "FreeBSD (64-bit)". - Workaround 2 is to not install acpitimer_delay() with delay_init() during acpitimerattach().
Maybe you noticed already, but in OpenBSD-Misc list I have suggested to make VMware Tools driver to advertise OS as 'FreeBSD 64-bit' OS, not 32-bit version, making workaround 1 a default system setting.
