Actually, after tracing through again, it appears to be following this codepath: (in reverse order from a backtrace) nv_alloc_pages() nv_free_vm_object() vm_object_deallocate() vm_object_clear_flag() atomic_clear_short() so I think it's possible that something may be getting screwed up between nv_free_vm_object and atomic_clear_short(). I'm not really sure how to tell though. Ken To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
