Hello Colin,

today I got the usual messages in dmesg which witness that kernel bug 
8740 is not yet fixed. Please add your patch to the tracker 
http://bugzilla.kernel.org/show_bug.cgi?id=8740 and set it to CODE_FIX 
as I have again to use i8042.nomux=1 to prevent these messages.

It is a very rare event but with i8042.nomux=1 it never happens, it has 
happened because I removed i8042.nomux=1 when I sent you the below 
message. The patch simply prevents me to set manually that kernel 
parameter, which is an annoyance.

Thank you,

Hi Colin,

I have removed 'i8042.nomux=1' from my kernel command line (kernel 
2.6.25-gentoo-r8) and the mouse glitches bug has not yet happened (last 
time I had 2.6.22 or so).

I assume it has been fixed in previous releases, and got unnoticed. I 
will reply again to this message if there is again necessity to use 
i8042.nomux=1.

Thanks for your help, and sorry for the noise.

Best regards,

I also have a notebook, Maxdata Pro 7000X (Fujitsu clone), which has
such problem (needs i8042.nomux=1, perhaps kernel bug #8740).

Can we also use a patch for it?
    

Can you test the patch below and see if it fixes the problem?
