WW47.5 Update:

Have verified the issue in ESXi5.1 / ESXi5.5 / ESXi6.0 /ESXi6.5 wit BIOS and EFI, can't reproduce it.

ENV:
Host: All ESXis
Guest: RHEL-7.5 with kernel-3.10.0-797.el7
FW: BIOS and EFI

Steps to Verify:
1. Boot the VM without fixes before install the kernel-3.10.0-797.el7
2. Check the dmesg for "..trying to set up timer (IRQ0) through the 8259A ..."
3. Update to kernel-3.10.0-797.el7, and reboot to this kernel
4. Check the dmesg again

Result:
1. After step 2, all machines, currently can't find "..trying to set up timer (IRQ0) through the 8259A ..."
2. After step 4, all machines, "...Host bus clock speed read from hypervisor..." could be found
