Bug ID: 272261
Summary: Crash on timer
Product: Base System
Version: 13.2-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: bugs@FreeBSD.org
Reporter: rozhuk.im@gmail.com
Got on 2 different installations in different virtualization platform.
Second start panic after system update, so something was broken after 14 apr.
Panic fast on heavy load.
Unread portion of the kernel message buffer:
