            Bug ID: 273543
           Summary: FreeBSD-15 kernel panic when the amdtemp device is in
                    the kernel
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Keywords: crash
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: gljennjohn@gmail.com

Including amdtemp in the kernel configuration file for FreeBSD-15 results in a
kernel panic at boot time.

A git bisect identified commit 9a7add6d01f3c5f7eba811e794cf860d2bce131d as the
cause.  This commit was made by Colin Percival on August 19, 2023, after
FreeBSD-15 was created, so this probably only affects FreeBSD-15 itself.

A user reported on current.freebsd.org that reverting this commit resolves the
panic problem.

A workaround is to kldload amdsmn.ko and amdtemp.ko.
