User-Agent: Mail/News 1.5 (X11/20060119) MIME-Version: 1.0 To: linux-kernel@vger.kernel.org Subject: 2.6.16_rc1 psmouse hangs without KVM Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello list, My first post to the linux-kernel mailing list - a little report on mouse hang experiences on a PS/2 mouse :-) Since the change from 2.6.14 to 2.6.16_rc1, I got mouse hangs using a first-generation MS IntelliEye Explorer with USB->PS2 converter, no KVM, which ran smoothly on the official 2.6.14. The syslog message is ... psmouse.c: resync failed, issuing reconnect request and I have the exact symptoms - hang after about 10 sec mouse inactivity, then after 2 secs it's back to normal - as described in the thread ... Date Mon, 9 Jan 2006 21:37:49 +0100 Subject Mouse stalls (again) with 2.6.15-mm2 between Jesper Juhl and Dmitry Torokhov. (http://lkml.org/lkml/2006/1/9/313) and a statement by Dmitry was to do resync retries every few seconds for KVM users. This certainly is a good idea for KVM users, but since Jesper and me are counter-examples to this frequent resyncing, I suggest that this is made an option in the kernel, like "KVM fixes - resync mouse in background". I personally had to turn off resyncing using the suggested echo -n 0 > /sys/bus/serio/devices/serioX/resync_time to get back the expected fluent behavior, since without a KVM, there is no automatic resyncing required ... Of course I stand ready for corrections or for giving more detailed info if required. ---- Ernst Rohlicek jun.
