Bug ID: 219070
Summary: vm_radix_remove: invalid key found panic
Product: Base System
Version: 11.0-STABLE
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: asmo...@freebsd.org

dmesg.boot after panic
This is an ASROCK Q2900 motherboard
(http://www.asrock.com/mb/intel/q2900-itx/).
Had similar panics with 10-STABLE and 11-STABLE and in the end replaced both
memory banks with new SO-DIMMS (Kingston KVR16LS11K2 in a 2-kit that's on their
supported memory list) and still received this. So I am excluding memory stick
issues.
The problem only seems to occur when under heavy load, say compiling ports with
poudriere or building world.
