 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,
