            Bug ID: 264179
           Summary: Boot hangs up with Alderlake's intel GbE NIC
           Product: Base System
           Version: Unspecified
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: yasu@freebsd.org

2 months ago I updated my home server to Intel Alderlake Core i3 12100 and
GIGABYTE H610I DDR4 (rev. 1.0) motherboard.

The latter has onboard Intel GbE NIC. But unfortunately 13.0-RELEASE doesn't
detect it. So I inserted Intel PCI-E GbE adaptor to the PCI-E slot of the
motherbord and used it as network interface of the server.

And now 13.1-RELEASE is released. I tried updating with `freebsd-update update
-r 13.1-RELEASE`, `freebsd install` and `shutdown -r now`. But after that
system hangs up in the middle of boot.

At first boot stops after onboard Intel GbE NIC is detected.

It keeps about a minute and then boot process resumes. But soon it stops again.

I waited about 20 minites in this state but boot never goes ahead.

Removing PCE-E GbE adopter doesn't change the situation.

I also tried boot image of 14.0-CURRENT 20220519 snapshot and boot hangs up
just same as 13.1-RELEASE.
