Description Enrico Paradiso 2022-03-15 10:55:15 UTC 
On my old       sony Vaio VGN-FE11H any freebsd iso (13.1-RELEASE, 12.3-STABLE) hangs at boot on acpi_dock0= station0.
No matter if I disable acpi e/o launch in safe mode.
Anybody could help me?
Thanks

Try booting with verbose mode, and show the last few lines that appear in the console before the hang.
Comment 2 Enrico Paradiso 2022-03-25 10:55:57 UTC 
hdaa0 :Pin sense :nid =14 sense =0x00000000 (disconnected)

Pcm2 :Recording Channel matrix is :2.0 (disconnected)

Last Lines after booting verbose and acpi on

I got the same on a fresh 14.0-CURRENT main-9a7c520a781

Pressing ^C causes the message

ACPI Error: Aborting method method \_SB.DOCK.EJ0 due to previous error (AE_ERROR) (20220331/psparse-689)

I didn't have this before on 14.0-CURRENT eb45bc6829157 but I am pretty sure I didn't load acpi_dock manually before. Now it autoloads.

This is also a VAIO, VGN-Z31VN

Remove _EJ0 call

Patch attached (for -CURRENT) removing acpi_SetInteger(handle, "_EJ0", 0) call
fixes this for me, probably not the "right" fix.

Apprently _EJ0 waits for undock to complete:

           Method (_EJ0, 1, NotSerialized)  // _EJx: Eject Device
            {
                UDKR = One
                Wait (UDKE, 0xFFFF)
                Reset (UDKE)
                Notify (^^PCI0.EXP4, Zero) // Bus Check
            }

On my system, this returns only after I remove the machine from the dock.

Full DSDT attached.

(In reply to Marcin Cieślak from comment #4)

I am sorry, this patch does not work. I get a hang every time I boot outside of the dock. (Waiting can be interrupted with Ctrl-C)
