ULE is the default in 7 as well. Perhaps remove some of the kernel
options not in 7, that are in 8 by default? What is the disk
subsystem ? just ata ?
They seem innocuous enough, but worth a try
options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4)
options MAC # TrustedBSD MAC Framework
options FLOWTABLE # per-cpu routing cache
