FreeBSD 15-CURRENT dmesg

Hi All,

I'm trying to get FreeBSD running on my personal laptop, but keyboard does not
seem to be working (but is recognized). The same behavior is exhibited on
14-RELEASE (memstick) and 15-CURRENT (memstick snapshot from 2024-04-25).

I am not aware of any quirks related to my specific model, neither in Linux,
nor in FreeBSD, nor am I aware of how to try them out and which.

The keyboard in question is attached internally via an i8042-compatible
controller (likely emulated in acpi?), so PS/2. Nothing else, that I'm aware of
is connected in such manner, and only keyboard is affected.

Relevant dmesg lines are:

atkbdc0: <Keyboard controller (i8042)> port 0x60,0x64 irq 1 on acpi0
ioapic0: Changing polarity for pin 1 to high
atkbd0: <AT Keyboard> irq 1 on atkbdc0
atkbd: the current kbd controller command byte 0067
atkbd: keyboard ID 0x41ab (2)
kbdc: RESET_KBD return code:00fa
kbdc: RESET_KBD status:00aa
kbd0 at atkbd0
kbd0: atkbd0, AT 101/102 (2), config:0x0, flags:0x1d0000
ioapic0: routing intpin 1 (ISA IRQ 1) to lapic 14 vector 50
atkbd0: [GIANT-LOCKED]
psm0: unable to allocate IRQ

But atkbd0 grabs IRQ1(?) (vmstat -i):

Also, full dmesg (also attached as file):
https://hastebin.com/share/avukayobob.yaml
pciconf -lv: https://hastebin.com/share/izehegiyen.java
dmesg on linux: https://hastebin.com/share/aliroqiwil.yaml
and, hw-probe (from linux): https://linux-hardware.org/?probe=8fa3424cce

I am willing to probe more and will try patches, but am out of ideas

And I'm not entirely sure on policy with external file hosts, so, if desirable,
will upload here, just don't want to unnecessarily bump my own report
