Bug ID: 225450
Summary: 11.1-* panics on AMD Opteron 2k due to
EARLY_AP_STARTUP
Product: Base System
Version: 11.1-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: pablo.r...@gmail.com
The EARLY_AP_STARTUP kernel option causes kernel panics on AMD Opteron 2xxxSE
CPUs. Including SUN X4100, X4200, etc.
Commenting EARLY_AP_STARTUP while building kernel allows boot. Safe mode boot
works too because it disables smp.
An svn bisect was performed for 11-stable and the addition of EARLY_AP_STARTUP
at r318763 seems to be the culprit.
This has been reproduced with 11.1-RELEASE, 11.1-RELEASE-p1, 11.1-RELEASE-p2,
11.1-RELEASE-p4 & 11.1-RELEASE-p6. Meanwhile FreeBSD 10 works/boots fine.
Example boot output with failing kernel (includes garbage):
/boot/kernel.old/kernel text=0x14972f8 data=0x1384c0+0x4c15e8
syms=[0x8+0x15e8b0+0x8+0x178422]
/boot/entropy size=0x1000
Booting...
