[PROBLEM] thinkpad_acpi: unhandled HKEY event 0x6040

[PROBLEM] thinkpad_acpi: unhandled HKEY event 0x6040

[Pekka Enberg]

Hello,

I'm seeing this when I dock a Thinkpad X220 laptop:

[ 3129.616279] thinkpad_acpi: unknown possible thermal alarm or
keyboard event received
[ 3129.616297] thinkpad_acpi: unhandled HKEY event 0x6040
[ 3129.616298] thinkpad_acpi: please report the conditions when this
event happened to ibm-acpi-devel@lists.sourceforge.net
[ 3129.616949] thinkpad_acpi: undocked from hotplug port replicator
[ 3129.617065] ACPI: \_SB_.GDCK - undocking
[ 3144.184916] ACPI: \_SB_.GDCK - docking
[ 3144.185204] ACPI: Unable to dock!

and the monitor doesn't come up.

I'm currently running a stock Fedora kernel:

[penberg@tux ~]$ uname -a
Linux tux 3.3.8-1.fc16.x86_64 #1 SMP Mon Jun 4 20:49:02 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux

but looking at drivers/platform/x86/thinkpad_acpi.c in Linus' tree, the event
is not handled there either:

        TP_HKEY_EV_UNK_6040             = 0x6040, /* Related to AC change?
                                                     some sort of APM hint,
                                                     W520 */

Help!

                        Pekka

The monitor doesn't come up because of something else, check the GPU drivers
and userspace.  And also why the docking failed...

Btw, I'm getting a similar thing when I unplug my x121e from AC:

[  613.517178] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[  613.533949] thinkpad_acpi: temperatures (Celsius): 60 0 60 0 0 0 32 0
[  613.536880] thinkpad_acpi: unhandled HKEY event 0x6040
[  613.539703] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net

this is when I plug it back:

[  623.308867] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[  623.322868] thinkpad_acpi: temperatures (Celsius): 60 0 60 0 0 0 32 0
[  623.322926] thinkpad_acpi: unhandled HKEY event 0x6040
[  623.322938] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net

All with 3.6-rc2 + tip/master.

Thanks.
