Thanks for babbling!

I'm having these same intermittent problems starting around 2.6.21, and 
wasn't really sure if it was hardware or not, so didn't bother reporting 
them.  This is what I see sometimes in the logs:

=====================================

psmouse.c: bad data from KBC - bad parity
psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, 
throwing 2 bytes away.
=====================================

Thanks!

Unfortunately I spoke too soon and some mouse warps occurred
yesterday. I suspect faulty hardware, so I'll try with my old
non-optical mouse. If it still happens then it's either the mobo
or the kernel. In the meantime I'll plug this one in another pc
and see if the warps happen there. After that it's running old
kernels to see if the warps happen there too. Any other ideas
to check whether it's a software or hardware problem?

The more annoying sticking key problem is gone for good though.

Greetings,

Indan

Thank you for testing the patches.

Since kernel 2.6.21 or so I was annoyed by a warping mouse, and
one kernel version later also by "stuck" keys, causing repeated input
at the most inconvenient moments (e.g. when opening a program by
pressing F1).

As it happened irregularly and unpredictable it was hard to debug,
and I suspected faulty hardware. My cpu was quite hot, but after
removing all the dust it seems all right again. Unfortunately that
was about the same time I upgraded to 2.6.23-rc1, so all I can say
is that the stuck key problem seems to be gone, though not sure
thanks to what, but that neither the cleaning nor the upgrade fixed
the warping mouse problem.

I'm running with these locking patches for two days now and the
mouse doesn't warp any more (it can also have fixed the stuck key
problem, not sure). Normally it would warp several times a day,
and that didn't happen yet, so I'm tempted to praise your patches.

Sorry for the babbling, just wanted to say that I've tested these
patches and that they seem to fix real problems.

Thanks,

Indan

Hi everyone,

I finally managed to put together some patches implementing
locking in input core and main input handles. Please look
over them and give them a spin.
