Message-ID: <20011112111409.A2617@socrates> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.23i From: Jeronimo Pellegrini Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello. The following patch (introduced by Vojtech Pavlik some time ago) was removed somewhere between 2.4.14 and 2.4.15-pre3. Without it, the timer counter is reset to a wrong value and gettimeofday() starts to return strange values. Nothing aboutit is mentioned in the changelog, so I suppose it wasn't supposed to be removed?
