Compiled self with option CPUTYPE?=nocona in /etc/make.conf GENERIC kernel run fine (dmesg.good). Without it during boot system freeze or freeze for 1 minute and then reboot in 90% tries after detect cd0 (no real dmesg, but I edit good dmesg to look same as real messages in console - dmesg.bad).

dmesg from boot -v with GENERIC kernel 11.2-RELEASE-p8 amd64

11.2 GENERIC kernel from freebsd-update boot fine.
But any 12.0 kernel freezes just after start.

Kernel from config MINIMAL freezes too just after start.
What can I do to find the cause?
Comment 8 VVD 2019-04-01 14:48:32 UTC
Why target-cpu detected as k6-3?

Comment 9 roel 2019-05-23 10:43:49 UTC
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.

BTW, clang 8 detect CPU as nocona in FreeBSD 11.3:
