Please do not put bugs on stable@, current@, hackers@, etc Placing this bug back on bugs@ to be triaged properly to a technical list
Kernel from config MINIMAL freezes too just after start. What can I do to find the cause?

This is the same issue as is reported in (amongst others) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235017 and https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233534. The issue is widespread and seems to be caused by incompatible hardware.
(In reply to roel from comment #9) 1st look same, yes.
