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.
