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
