(jaunty) psmouse.c touchpad synchronization issues

[Nicolò Chieffo]

I'm running jaunty 2.6.28-5.15-generic, and I have a dell laptop, with a hardware wireless and bluetooth swith. when I change the wifi and bluetooth from ON to OFF, I always get this message in syslog:

psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 lost synchronization, throwing 4 bytes away.
psmouse.c: resync failed, issuing reconnect request
psmouse serio1: ID: 62 02 14<6>elantech.c: unexpected magic knock result 0x07, 0x02, 0x64.
input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input14

the ALPS touchpad reconnects as a normal mouse, so I loose its functionality.
What can I do?
Thank you very much

Hi Nicolo,

What happens if you unload and then reload the psmouse module. Thanks.

I get my touchpad back again! good!!

[Nicolò Chieffo (yelo3)]

Is it possible to do this automatically?

[Nicolò Chieffo (yelo3)]

This might also happen when disabling wifi from network manager,
without using any hardware switch.

[Nicolò Chieffo (yelo3)]

It seems that this issue is no more present: I disabled wifi 10 times,
and no issue was detected.
Before closing this I will do some other tries too

Now it's back again. In fedora with kernel 2.6.29 this bug does not seem to be present

This also happens disabling wifi through network-manager

fixed for me in linu-image 2.6.28-8.27
