https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218663 Bug ID: 218663 Summary: atal trap 12: APU2C4: CURRENT (r316857): Fatal trap 12: page fault while in kernel mode (syslogd) Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: ohartmann@walstatt.org CURRENT as of r316857, fails to boot kernel on PCengines APU 2C4 with the error shown below. r316717 runs fine (exact same ports, exact same config). It seems the kernel to be the culprit, I can easily swap the kernel rr316857 with its according userland (also r316857) with the kernel r316717 and everything is fine.
