I have added a single-user core dump. It contains a few commonalities with
multiuser, that being:


Firmware Error (ACPI): Could not resolve symbol [\134_SB.PCI0.LPC0.EC0],
AE_NOT_FOUND (20250807/dswload2-315)
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20250807/psobject-372)
Firmware Error (ACPI): Failure creating named object
[\134_SB.PCI0.GPP6.WLAN._DSM], AE_ALREADY_EXISTS (20250807/dswload2-480)
ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog
(20250807/psobject-372)
[...]
acpi_timer0: <32-bit timer at 3.579545MHz> port 0x408-0x40b on acpi0
acpi_ec0: <Embedded Controller: GPE 0xb> port 0x62,0x66 on acpi0

Additionally, I looked at the dev tree and found:

0x10-0x1f (acpi0)
0x20-0x21 (unknown)
0x22-0x3f ----
0x40-0x43 (attimer0)
0x44-0x5f ----
0x60 (atkbdc0)
0x61 (unknown)
0x62 (acpi_ec0)
0x63 ----
0x64 (atkbdc0)
0x65 ----
0x66 (acpi_ec0)
0x67-0x6f ----
0x70-0x71 (atrtc0)
0x72-0x73 (acpi0)
0x74-0x7f ----
0x80 (acpi0)

This suggests to me that this is an issue with a few protocol initializations,
which sounds like a PSP issue due to PSP being a nonepci return in pciconf.
