I'm running 3.4.0 on a Thinkpad T420s.  It works well nearly all of the
time, but recently I got the following message when I unplugged the AC
adapter:

[17037.973595] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[17037.973599] thinkpad_acpi: unhandled HKEY event 0x6040
[17037.973601] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net

So, here's a report. :)

It's possible that I accidentally hit the keyboard or something while
unplugging the power.

I don't get this message every time I unplug the power.

Please find below the other relevant parts of dmesg, and dmidecode.

Thanks,
-andy

Thanks for the report.  Please ignore this issue for the time being.

Andy, as an early follow up, does it make any difference whether you
plug/unplug AC power directly on the notebook, or on a docking
station/port replicator?

Do you have more than one power brick with different power ratings (e.g.
65W and 90W)?

Because AFAIK you really should get a 0x6040 every time the AC power
adapter state changes.

I do use two or three different PSUs, they may have different ratings.
The one I have in front of me is 65W, and I do get 0x6040 when I plug or
unplug it today.  The other one is at the office and I'll check on
Monday.

Looking through syslog, I do have a lot of pairs of "unhandled HKEY
event 0x6040" followed immediately by "EC reports that Thermal Table has
changed", but there are also a few Thermal Table changed without a
preceding HKEY event.  Perhaps 90% of "Thermal Table has changed" have a
HKEY before them.  There don't appear to be any HKEY 0x6040 without a
"Thermal Table has changed" immediately after.
