Ah, sorry for insufficient info last time.

Now, I'm carrying out some stress tests on two landisk boxes for
-current as of today with:

$NetBSD: uvm_map.c,v 1.421 2024/08/14 01:26:25 riastradh Exp $

(1) Full ATF run on DIAGNOSTIC kernel:

A lot of "kernel weak diagnostic assertion" failures as before,
but panic has not occurred so far. Now, it comes to:

net/if_ipsec/t_ipsec_natt (549/954): 2 test cases

(2) Build pkgsrc's on DIAGNOSTIC kernel:

Panic has not occurred yet so far.

I will continue the tests, and get back to you...

Thanks,
