Repeated panics on a Proliant 800 biproc with 1.6D kernel and 1.5.2 userland

[posted to tech-kern, current-users, tech-smp, please feel free to
restrict the followup to tech-kern]

Context :
---------

Compaq Proliant 800, bi PII/400 (dmesg later)

1- Installed 1.5.2 relaese on this machine (latest snapshot,
20020518-1.5ZC panics when installing)

2- Imported -current source tree.

3- copied a GENERIC-1.6D kernel build on another machine running
up-to-date NetBSD-current, then rebooted.

4- Started to rebuild the userland (previous hazardous experiments told
me to do the compile in a single pass into /, to avoid lib and toolchain
conflicts)

5- Almost immediate panic. Actually, not a panic, but a NMI !
(copied by hand, no serial console on the machine)

| NMI ... going to Debugger
| Stopped in pid 1153 (cc1) at pmap_zero_page+0x3d  repe  stosl %es:(%edi)

| trap() at trap+0x4d4
|    --- trap (number 6) ---
| 0x80cb664

I dunno which device is responsible for the NMI .... Perhaps the kernel
thinks the second (actually unused drive is part of a RAIS frame ?)

Here is dmesg :
