If I compile with any CLK or HZ option, the system time goes ballistic. If I leave them out. I get kern.timecounter.method: 0 kern.timecounter.hardware: i8254 Setting these same options via sysctl.conf doesn't help, nor does changing them. I really think this is a code issue in -STABLE, but may be wrong. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
