 Hi, unfortunately the problem is still present. Although I did get a
 slightly different panic today on a DIAG+DEBUG+LOCKDEBUG kernel:
 
 panic: kernel diagnostic assertion "RB_BLACK_P(self)" failed: file
 "/usr/src/sys/lib/libkern/../../../common/lib/libc/gen/rb.c", line 780
 kern_assert()
 rb_tree_remove_node()
 npf_conndb_remove()
 npf_conn_gc()
 npf_worker()
 
 I am now running a kernel with KTHREAD_MPSAFE commented out on the
 npf worker thread to see if it makes any difference. (This will prevent
 network stuff from preempting the worker thread right?)
 Anything else worth trying?
