psmouse serio4: bad data from KBC - timeout

[Borislav Petkov]

Hi guys,

I'm running 3.4-rc1 on a thinkpad x121e and it builds and boots just
fine. However, after resuming from disk I get (this is the tail of
dmesg):

[  905.857412] i8042: failed to resume active multiplexor, mouse won't work

Any help is appreciated,

There weren't any changes to i8042 for a while so I'd look into recent
ACPI/PM merges. You can also try booting with i8042.nomux to see if it
will work better with i8042 in legacy multiplexing mode.

Thanks.

thanks for looking into this.

So, I just tested the "i8042.nomux" command line option and it seems to
work. Even the touchpad went on after rubbing on it a couple of times
initially.

Then, I booted back into 3.4-rc1 without the above option and here's
what I got again:

It seems the mux controller doesn't resume properly (doh, it says so
:)) so not only mousepad but keyboard is not working too.

Actually, that's not 100% correct: the keyboard does work for a short
period of time (a couple of seconds, judging by the printk timestamps
below) right after I resume and then it stops ...

.. with the above being the last line on dmesg.

So, I'm ready for suggestions.

As I said I would start at the latest ACPI and PM merges and try
reverting them - i8042 may interact in funny ways with embedded
controller since it is usually the same piece of firmware.

I assume it works fine in 3.3, right?

As I said I would start at the latest ACPI and PM merges and try
reverting them - i8042 may interact in funny ways with embedded
controller since it is usually the same piece of firmware.

I assume it works fine in 3.3, right?

Yes, it does.

Let me checkout git trees before those merges to see whether it makes
any difference.

Well, what do you know, I checked out the commit before Len's ACPI pull request:

git checkout a335750b9a039a9d4cd727cdccacfb90fd63c4e8~1

I.e., the tree I'm currently testing has
