Hi,
I still have troubles with mouse, it keeps jumping here and there and I
see lots of messages in logs:
Feb 27 20:49:55 dreamland kernel: psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.
Feb 27 20:50:42 dreamland kernel: psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.
Feb 27 20:51:11 dreamland kernel: psmouse.c: bad data from KBC - bad parity
Feb 27 20:51:11 dreamland kernel: psmouse.c: bad data from KBC - bad parity
Feb 27 20:51:12 dreamland kernel: psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.
Feb 27 20:55:32 dreamland kernel: psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 2 bytes away.
Feb 27 20:58:38 dreamland kernel: psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.
These happened while surfing web with little activity on eth0 and while disks
were almost idle (-u1 is set on both of them). Using vmstat I see that
I'm getting around 1300 interrupts per second while moving mouse (less
than 1100 while doing nothing), so I don't think that there's something
spinning in ISR for too long.
Problem first appeared in 2.6.2, 2.6.1 is unaffected. I see that in
2.6.3 there's a patch which is supposed to fix this, but it still
happens for me.
Any clue?
Luca

The bad parity messages definitely suggest a problem with the mouse
cable - either too long or broken.

Hum, but why does it work with older kernels? If I boot with 2.6.1 it
works without problems.
thanks,

2.6.1 ignores bad parity in mouse data.

Oh, I see. Thanks for the clarification, I'll try and see if I can
reproduce with another mouse.
