Yes the time counter choice priority changed , in 8 favoring higher precision hardware like hpet over acpi-fast/safe . I am not sure why or when thus was done; or if this is a side effect of another change. Interestingly centos/rhel/suse has made similar changes and VMware has odd issues with them as well.
Can you boot up a 7 environment and get us the value sysctl kern.timecounter . Then get that from an a 8 and 9 environment . Then if the 7 environment uses a different time counter can you try using that value on your crashing setup and report back what the result is .
