PATCH 1/1 input: Thinkpad R31 i8042 nomux quirk

Subject: [PATCH] input: Thinkpad R31 i8042 nomux quirk
from: Colin B Macdonald <[email protected]>

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:

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.

[ 3203.407979] psmouse.c: issuing reconnect request

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,
