--- Comment #23 from jschachter@spendata.com <jschachter@spendata.com> ---
Something very similar is happening to me trying to UEFI boot the
FreeBSD-14.3-RELEASE-amd64 installer off a USB stick on my new Dell laptop.  

The laptop has an NVMe SSD and I wonder if NVMe is the common thread between
the reporter's problem and mine.

What happens to me is this: 

(1) I boot the laptop with the FreeBSD USB stick attached, and press F12 for
the boot menu.

(2) I select the USB stick from the UEFI boot menu.

(3) The FreeBSD boot screen is displayed.  I tried both "Boot Installer" and
"Boot Single user" and get the same result...

(4) The boot proceeds until it shows "pci6: <ACPI PCI bus> on pcib8" and then
it hangs.  I've left it for 10 minutes and it did not continue, so I doubt it
ever will.   The keyboard is not responsive.  I do not see any errors in the
boot messages, unlike the reporter.

---

I checked the installer's /boot/loader.conf and the associated .conf files and
did not find any that contain ig4_load="YES", in fact there is no appearance of
the string "ig4" in any of the files.


Here is my /boot/loader.conf:

  vfs.mountroot.timeout="10"
  kernels_autodetect="NO"
  loader_menu_multi_user_prompt="Installer"

I have not altered it - this is what came with the installer.

/boot/defaults/loader.conf contains much more, but again, it all comes with the
installer - I did not change any of it.

Other notes:

- Secure boot is disabled.
- TPM 2.0 Security is OFF.
- In the BIOS, "SATA/NVMe Operation" is set to "AHCI/NVMe".  The only other
option is "Disabled", which is not selected.
- I am able to boot Ubuntu from another USB stick.
- I did try commenting out vfs.mountroot.timeout="10". Same result:  hangs
after showing "pci6".

I welcome any suggestions on how to gather more information from my system as
it boots.  I'm stumped.
