DragonFlyBSD

This is x86_64, right?

At least I get those messages too on my x86_64 laptop.

That's correct, its a 64Bit laptop. If you google that model your find the full
specs.

Which DragonFly did you run:
DragonFly/i386 or DragonFly/x86_64 ?
(both are possible on current 64bit systems)

Also: which version 2.4-release, head or ..?

This issue also seems like what you reported in issue 1589;
it might be worth following up on that.

See kernconf(5) & build(8) for a bit more info on
platform/arch supported in DragonFly.

64Bit, Head.

1589 was another issue, this looks to be somewhere else as the patch in 1589 was
already applied and solved the message on that hw from memory.

Cheers,
Edward.

I guess you were running DragonFly/x86_64, right?
(I don't see it from your answer in prev. message)

Please update issue 1589 with info in your prev. message.

Can someone try this patch please?
I no longer have access to the hardware and would like to see this fixed.

Reopening, what I committed is actually a fix to a regression introduce (I
think) with ac779aee61cac... ~Feb 14

Fixed in commit d21705bcc1c27c7b99fbd88bf6cb34a58add4666
Many thanks to Sascha Wildner!
