Subject: [PATCH] input: Thinkpad R31 i8042 nomux quirk
from: Colin B Macdonald <cbm@m.fsf.org>
Thinkpad R31 needs i8042 nomux quirk. Stops jittery jumping mouse
and random keyboard input. Fixes kernel bug #11723. Cherry picked
from Ubuntu who have sometimes (on-again-off-again) had a fix in
their patched kernels.

Hello,
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?
dmidecode useful information:
Handle 0x0001, DMI type 1, 25 bytes
System Information
Manufacturer: MAXDATA
Product Name: Pro 7000X
Version: xxxxxxxxxx
Serial Number: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
UUID: xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxxxxxxxxxxxx
Wake-up Type: Power Switch
Thanks,

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

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,
--

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,
