            Bug ID: 289007
           Summary: Slow boot on AMD Framework 13/16 with FreeBSD main
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: misc
          Assignee: bugs@FreeBSD.org
          Reporter: jrm@freebsd.org

Framework 16 owners are experiencing very slow boots when running FreeBSD main.
 FreeBSD 14.3 on the same laptop boots normally.

I tried replacing the bootloader on a 14.3 install image with one built from
main, but the 14.3 image still booted quickly.

At BSDCan, some people reported that the AMD Framework 13 had the problem, but
it was fixed.  Another Framework 13 user said his system still boots slowly
with a recent main snapshot.

I'll add more information here as I learn more.

Comment 20 from bug 254381 seems to be the same issue.
