I've updated an oracle ampere instance running -current from
2024-09-12-140543 to 2024-10-30-121420 and now I get:
---snip---
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...
Loading splash ok
No valid device tree blob found!
WARNING! Trying to fire up the kernel, but no device tree blob found!
---snip---

I don't see anything in UPDATING about changing the kernel config...
what did I miss?
. . .

One possibility is this was an ACPI based boot.

Booting ACPI (such as via EDK2 use with ACPI selected) normally
produces the messages:

No valid device tree blob found!
WARNING! Trying to fire up the kernel, but no device tree blob found!

I've got a bunch of historical ACPI-based boot logs with that text,
including this year, not just many prior years. An example
extraction is:

. . .
Loading configured modules...

/boot/entropy size=0x1000

/etc/hostid size=0x25

No valid device tree blob found!

WARNING! Trying to fire up the kernel, but no device tree blob found!

---<<BOOT>>---
. . .


The lack of a device tree is the normal case for ACPI based booting.
I do find this part of the messaging for an ACPI-based boot
misleading.

It doesn't boot at all. It hangs after this message.
The previous BE boots just fine, so something is broken.

Bye,
Alexander.
