psmouse lost sync / resync failed

[BC7333]

Linux brian-laptop 2.6.24-12-rt #1 SMP PREEMPT RT Thu Mar 13 00:49:29 UTC 2008 i686 GNU/Linux

Hardy beta upgraded from Gutsy.

experiencing lost mouse synchronization / resyncthis quite frequently. Happens very often, 2 or 3 times in 5 mins or less.

iwl3945 intel pro wireless (possibly related)

Logs show?

Mar 24 13:35:26 brian-laptop kernel: [ 3674.896275] psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.
Mar 24 13:35:26 brian-laptop kernel: [ 3674.983841] psmouse.c: resync failed, issuing reconnect request

Happened some with feisty, more with gutsy and a lot more with hardy. probably two or three times worse than with Gutsy.

Often Firefox will simply close and / or programs in the menu will appear.

dmesg, version, lspci logs attached.

Thanks!

This happens to me as well. It happens at startup, but then not anytime afterwards unless the computer is at 100% cpu

mlapaglia,

Thanks for the tip about cpu.. when I use powersave mode with KPowersave that forces cpu to 800 instead of 1200 it seem to help quite a bit, but still hapens eventually. Still a marked improvement.

I also experienced similar flakey mouse movements before in feisty/gutsy when wireless was trying to connect but don't have the logs to confirm this.

Hi, I'm not sure where to post, it seems i know the same bug as mentioned here.

primarly posted with attached dmesg.log and lspci-vvnn.log: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/119194

The mouse pointer move itself to some of the corners of the desktop and frenetically click either left or right button while approximately one second.
I can add that the keyboard may seem to press itself some of the last "really key pressed".

Of course.. all possible actions which were met in the mouse path happens : software close, some other "open with", gnome-session stop etc...) all that depending on what's on your desktop at this time (and the icons or applet in your desktop corners).

All worked fine for several months ; I do apply all official updates as soon as they come and have just updgraded to Hardy as adviced here. (nice to meat hardy)
The bug began for me near the 2008 march 15 (after an update?)

I add, that I didn't realize that it may be related to a little bluetooth usb key i did not often use before. I'll try the pc with this key off (lsusb =>0a5c:200a Broadcom Corp. Bluetooth dongle) - why not :)

syslog always says that at the exact time of "this event" :

hi,
Sorry to mention that if my bluetooth is unplugged, the pointer still move and click (especialy on top corners, but not only), same dmesg ../.. boring ... but no stress :) A pity i didn't save all my logs the first time this event happened. (Lesson 1 !)
Thanks
