https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237470 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: luporl Date: Tue Apr 23 17:11:45 UTC 2019 New revision: 346600 URL: https://svnweb.freebsd.org/changeset/base/346600 Log: [PPC64] Fix wrong KASSERT in mphyp_pte_insert() As mphyp_pte_unset() can also remove PTE entries, and as this can happen in parallel with PTEs evicted by mphyp_pte_insert(), there is a (rare) chance the PTE being evicted gets removed before mphyp_pte_insert() is able to do so. Thus, the KASSERT should check wether the result is H_SUCCESS or H_NOT_FOUND, to avoid panics if the situation described above occurs. More details about this issue can be found in PR 237470.
