I can confirm Andrea&#39;s findings 100% it sums it up for me completely. Especially that there is no relation between inplugging / outplugging of the battery. <br>On the side, my now 80% complete switch to mandriva to avoid this bug learned me that (k)ubuntu should drastically improve its kde integration... <br>
<br>I any testing on a dell needs done I&#39;m available with a D830. <br><br><div class="gmail_quote">On Mon, Jun 9, 2008 at 2:54 PM, Andrea Ratto &lt;<a href="mailto:andrearatto_liste@yahoo.it">andrearatto_liste@yahoo.it</a>&gt; wrote:<br>

1 battery or not battery it happens<br>
2 it starts when using again the touchpad after a period of inactivity. (Maybe on battery this period can be shorter)<br>
when it starts it freezes everything for some seconds, CPU usage get to 100% on all cores. At this point if you keep insisting on the touchpad you can really crash the machine. If you let go it usually just pass but you have to notice quickly.<br>

3 sometimes the touchpad looses touchpad functionalities (eg scrolling on the right border).<br>
4 dmesg entry &quot;psmouse.c: GlidePoint at isa0060/serio1/input0 lost synchronization, throwing N bytes away.&quot; not always shows.<br>
5 many people are having this problem, someone also on fedora, someone since 2.6.15, mostly on dell laptops.<br>
<br>
I think I could get to reproduce it anytime I want, so I can produce any<br>
debug/crash information. Just tell me what to do and I&#39;ll do it.<br>
