Thoughbook CF-30 strange boot timeouts

I have successfully installed Freebsd 13.0 on old CF-30 Panasonic Thoughbook. Basically, it works, but the boot process is very slow due to some device not being responsive:

Code: 
Root mount waiting for: CAM
Root mount waiting for: CAM
Root mount waiting for: CAM
Root mount waiting for: CAM
Root mount waiting for: CAM
Root mount waiting for: CAM
Root mount waiting for: CAM
...


At some point the device times out:
Code: 
...
(aprobe0:ata2:0:1:0): ATAPI_IDENTIFY. ACB: a1 00 00 00 00 40 00 00 00 00 00 00
(aprobe0:ata2:0:1:0): CAM status: Command timeout
(aprobe0:ata2:0:1:0): Retrying command, 0 more tries remain

...

(aprobe0:ata2:0:1:0): CAM status: Command timeout
(aprobe0:ata2:0:1:0): Error 5, Retries exhausted
Root mount waiting for: CAM
...
(aprobe0:ata2:0:1:0): ATAPI_IDENTIFY. ACB: a1 00 00 00 00 40 00 00 00 00 00 00
(aprobe0:ata2:0:1:0): CAM status: Command timeout
(aprobe0:ata2:0:1:0): Retrying command, 0 more tries remain
Root mount waiting for: CAM
...

And then it gives up after which the boot process continues normally:
Code: 
(aprobe0:ata2:0:1:0): ATAPI_IDENTIFY. ACB: a1 00 00 00 00 40 00 00 00 00 00 00

I need help debugging this issue:
1) I don't know how to check which device is that (aprobe0:ata2:0:1:0)
2) Perhaps there is a way to disable the device

I'm attaching dmesg / pciconf / kldstat to this post

Keyboard, internal mouse, external mouse and external USB hard drive. My bad. I should have presented the information with minimal possible amount of devices. I will do that tomorrow.

But I'm not hoping someone could figure out the problem just looking at the dmesg output. What I'm asking is an advice on how to debug such problems, for example, how to relate the device path "aprobe0:ata2:0:1:0" to some real /dev entry.
 
I have a slow external USB drive and in put /boot/loader.conf
Code: 
hw.usb.no_boot_wait="1"  # DO NOT WAIT FOR USB DEVICES FOR ROOT (/) FILESYSTEM

camcontrol devlist show the devices which can be interesting to know. It is listed without /dev prefix.
Code: 
camcontrol devlist
 
sure,
Code: 
# camcontrol devlist
<MATSHITA DVD-RAM UJ-841S 1.00>    at scbus0 target 0 lun 0 (pass0,cd0)
<KINGSTON SQ500S37240G SBFKB1D1>   at scbus1 target 0 lun 0 (pass1,ada0)
<AHCI SGPIO Enclosure 2.00 0001>   at scbus5 target 0 lun 0 (pass2,ses0)

That AHCI SGPIO Enclosure 2.00 0001 bothers me a bit, but it supposed to provide information on sensors/battery level.
 
Perhaps ata2 in aprobe0:ata2:0:1:0 points to pass2 in at scbus5 target 0 lun 0 (pass2,ses0) ?
 
Hm. The hint.ata.2.disabled="1" worked like charm! And, guess what ?
Code: 
# camcontrol devlist
<KINGSTON SQ500S37240G SBFKB1D1>   at scbus0 target 0 lun 0 (pass0,ada0)
<AHCI SGPIO Enclosure 2.00 0001>   at scbus4 target 0 lun 0 (pass1,ses0)
That "enclosure" device is gone! Which means I was, perhaps, right when I said that ata2 points to pass2.

Now. I only have to figure out which bits and pieces were disabled with that ses0...

Hey!!! the xfce battey manager applet suddenly starts working (it was failing before). Hm... Hm.... I wonder what that ses0 device was for, but turning it off brought me some good.
 
Oh, wait, no...
Code: 
# kldload ahci
kldload: can't load ahci: module already loaded or in kernel
So it was there all time long.

Well. I feel like that monkey from Futurama when it had his magic hat destroyed: kinda happy.

If your's is in this list the kernel should detect it. If not probing can take time.
 
I am too tired at this point, but I will find out what chipset this AHCI SGPIO Enclosure 2.00 0001 device is built on. It seems to be pretty ... common on servers.
 
I'm re-reading the thread and I see that I've missed the question:
Is ACPI enabled in the BIOS?.

Yes, it IS enabled in BIOS and I can # acpiconf -s 3 successfully.....
