Harumph!

The expected / valid distance value range (as per ACPI spec) is
[10, 255] (actually double-checking the spec, 255 is supposed to mean
"unreachable", but whatever)

Now, something in your system is exposing 256 nodes, all of them distance 0
from one another - the spam you're seeing is a printout of

  node_distance(i,j) for all nodes i, j

I see ACPI in your boot logs, so I'm guessing you have a bogus SLIT table
(the ACPI table with node distances). You should be able to double check
this with something like:

$ acpidump > acpi.dump
$ acpixtract -a acpi.dump
$ iasl -d *.dat
$ cat slit.dsl

As for fixing it, I think you have the following options:

a) Complain to your hardware vendor to have them fix the table and ship a
   firmware fix
b) Fix the ACPI table yourself - I've been told it's doable for *some* of
   them, but I've never done that myself
c) Compile your kernel with CONFIG_NUMA=n, as AFAICT you only actually have
   a single node
d) Ignore the warning


c) is clearly not ideal if you want to use a somewhat generic kernel image
on a wide host of machines; d) is also a bit yucky...

There does not seem to be a SLIT table in my firmware:

The hardware is probably too old for the vendor to care about fixing it.

Shouldn't the kernel be able to cope with quirky hardware? From what I remember in the past,
ACPI tables used to be broken quite a lot and the kernel contained workarounds for such cases,
didn't it?

Huh, then this might be some initialization fail that leaves nr_node_ids to
MAX_NUMNODES, which must be 256 in your case (NODES_SHIFT=8). Devicetree
can provide node distances, but something tells me you're not using that :-)

Technically it *is* coping with it, it's just dumping the entire NUMA
distance matrix in the process... Let me see if I can't figure out why your
system doesn't end up with nr_node_ids=1.

Does the below
a) compile
b) do anything?

From what I could gather, nothing actually tickles the possible map for
ia64. The standard pattern seems to be

        node_possible_map = numa_nodes_parsed;

but here at a quick glance it seems it's online or nothing, so that's what
I went for.

HTH.

It fixes the problem for me.

I also poked at it a few days ago assuming it was an issue causing boot
failures (it was not, it's a harmless warning).

Looking at 'arch/ia64/**' NUMA presence is detected by SRAT ACPI
tables (and generic ACPI also wants SLIT, those probably exist on large
ia64 boxes?)

None of SRAT/SLIT are present on these small machines, thus I would
expect generic code to  erive single fake node. Boot log suggests we even
inferred 1 node system:

> [    0.040000] smp: Brought up 1 node, 4 CPUs

Or is it just an early bootstrap message assuming more are to come?

Could it be that we initialize too little of generic acpi boilerplace
when there is no SRAT? Somewhere around:

    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/ia64/kernel/acpi.c#n446

arm64 and riscv calls `arch_numa_init()` and initializes numa node
data in numa_init().
While ia64 only calls acpi_numa_init() but not arch_acpi_numa_init()
(which would do numa_init() for us).

x86 seems to vaguely resemble generic code by duplicating numa_init().

(UNTESTED) Could it be that we need something like:

--- a/arch/ia64/kernel/setup.c
+++ b/arch/ia64/kernel/setup.c
@@ -571,7 +571,7 @@ setup_arch (char **cmdline_p)
        acpi_table_init();
        early_acpi_boot_init();
 #ifdef CONFIG_ACPI_NUMA
-       acpi_numa_init();
+       arch_numa_init();
        acpi_numa_fixup();
 #ifdef CONFIG_ACPI_HOTPLUG_CPU
