This is an APU2; I've got a bunch of them in the field (one is m= y own personal firewall/gateway) but they're EOL'd as the SOC w= as deprecated.=C2=A0 They run quite well and I'm on stable/14 with t= hem at present.

After a recent update a few weeks back I was not able to connect by COM
port anymore - console output and input went away after booting and
before single- or multi-user mode would start. Even re-flashing the
SDcard with a fresh image did not help.

After some longish trials and errors it turned out that both - commit 74b9fc7a 'amd64 GENERIC: Switch uart hints from "isa" to
"acpi"' as well as
- commit 4ba4cfaf 'acpi: Narrow workaround for broken interrupt settings
on x86'
broke things for me. Restoring hints and setting
hw.acpi.override_isa_irq_polarity=3D1 in /boot/loader.conf.local restored
working order.

I agree that APU1 is EOL, however I would have expected an entry to
UPDATING for such a POLA violation.

Likely, but really really old gear like this is going to hit edge cases that
developers haven't seen. The hint thing wasn't thoug= h to actually negatively
affect any deployed hardware since it dealt with details that changed 15 or
20 years ago...

Looks like the APU1 used coreboot which at the time was trailing adaptation
of ACPI, so it makes sense... I knew that Soekris boxes had issues, but they
are another 5 or 10 years older than the APUs and mine sadly isn't operational.

So I can write a better UPDATING entry, can you share with me the dmesg
from both APU1 and APU2?

Note that pc-engines APU2 models are not affected as the BIOS ACPI
tables contain correct UART descriptions.
