https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242961 --- Comment #8 from Mark Johnston <markj@FreeBSD.org> --- I found a bug by causing some of my desktop applications to dump core. I suspect this is what you are hitting. TTM uses the plinks.q fields for its own purpose, but we were inadvertently putting TTM-managed pages on the global page queues. diff --git a/sys/vm/vm_page.c b/sys/vm/vm_page.c index e99732028af5..971d8a0ed236 100644 --- a/sys/vm/vm_page.c +++ b/sys/vm/vm_page.c @@ -4013,7 +4013,7 @@ vm_page_mvqueue(vm_page_t m, const uint8_t nqueue, const uint16_t nflag) KASSERT(nflag == PGA_REQUEUE || nflag == PGA_REQUEUE_HEAD, ("%s: invalid flags %x", __func__, nflag)); - if ((m->oflags & VPO_UNMANAGED) != 0) + if ((m->oflags & VPO_UNMANAGED) != 0 || (m->flags & PG_FICTITIOUS) != 0) return; old = vm_page_astate_load(m); -- You are receiving this mail because: You are the assignee for the bug.help
