Hi: (1) Fully updated with test repos. Thinkpad W520. I have kernel 3.2.5-1. I see this in logs: lap3 kernel: [282571.053156] thinkpad_acpi: unknown possible thermal alarm or keyboard event received lap3 kernel: [282571.053160] thinkpad_acpi: unhandled HKEY event 0x6040 lap3 kernel: [282571.053161] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net (2) lsmod shows thinkpad_acpi is running. I found in /lib/modules was kernel/drivers/platform/x86/thinkpad_acpi.ko.gz and possibly kernel/drivers/acpi/acpi_pad.ko.gz The first one seems to be version 0.24 but I cannot tell if its the 0.24-20110604 version or earlier - at least by poking at the .ko. (3) http://sourceforge.net/projects/ibm-acpi/files/thinkpad-acpi/0.24-20110604/ Suggests this is/may be fixed in this version - could our version of thinkpad_acpi be out of date? Thanks gene
