Veldhouse" To: Subject: microuptime() went backwards (50596.915024 -> 50596.895202) Date: Mon, 26 Feb 2001 10:51:02 -0600 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4133.2400 X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4133.2400 Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I seem to have a problem unique to my Athlon system. I noticed this problem begin somewhere around 4.2-STABLE. The message: microuptime() went backwards (50596.915024 -> 50596.895202) is repeated thousands of times and floods my syslog when the system under load (currently during a buildworld). The times vary of course. What changes have been made relatively recently to cause this error? This seems to be a problem for either Classic Athlons or it has also been speculated by a couple to be VIA KX133 related. Please advise.
