Bug ID: 225799
Summary: HP P2-1310: System hangs on boot unless
kern.smp.disabled=1 is set
Product: Base System
Version: 11.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern

Boot log from successful boot
System is an HP P2-1310 box with "AMD E2-1800 Accelerated Processor".
When running FreeBSD 11.1, the system will hang on boot unless
"kern.smp.disabled=1" is in /boot/loader.conf or unless "Safe Mode" (which adds
that option plus some others) is selected.
This bug seems like it is probably related to
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220277 (Bug 220277), however,
compiling a kernel without EARLY_AP_STARTUP does not help, and applying the
code patch to OsdSchedule.c from that patch does not help either.
The bug seems to exist in the current (as of a few days ago) 11 STABLE as well.
As I want to run vbox from time to time, I would really like all my cores to be
usable..
Attached is /var/run/dmesg.boot from a successful boot (ie kern.smp.disabled=1
is set).
