BIOS or kernel ACPI bug. In both cases, try with 2.6.22 and 2.6.23 first, with the latest thinkpad-acpi patch from ibm-acpi.sf.net, and an extra patch you will find in the linux-thinkpad ML that changes KEY_BRIGHTNESS_UP/DOWN to KEY_RESERVED in the default keymap for Lenovo thinkpads. > Some of the FN-Fx combinations do not work as expected: > table created after "echo enabled > /proc/acpi/ibm/hotkeys" and "echo 0xffff > > /proc/acpi/ibm/hotkeys" The above is wrong if you want all keys, and you don't need to do anything to get they working properly by default, either [with the patch in the linux-thinkpad ML, otherwise, you have to disable the brightness up/down keys in thinkpad-acpi hotkey_mask, or you have to use input-kbd to remap them to KEY_RESERVED (keycode 0)]. It is no wonder it doesn't work well after such commands. Read the documentation for thinkpad-acpi that is in the Documentation/thinkpad-acpi.txt file. > FN+F4 223* 00001004* 142* > FN+F10 FN is shown** no reaction 143*** > FN+F12 165* 0000100c* 205* > > * keys work only sometimes, i.e. after some time again, but never two times > consecutivly. This is correct, and it is behaviour defined in firmware. These are sleep keys. They do NOT have to send events more than once at all. It is in the documentation. > ** while holding the key down, a *lot* of keypress events are triggered. I have no idea what is causing this.

Nothing I can do about it, but you can complain to Lenovo and ask for a fix. > What can I do to get at least the Mute and Power button working ? Try kernel 2.6.22.y latest. If that works, try 2.6.23.y latest. If that doesn't work, we can try debugging things further, but it is extremely likely you have a BIOS or EC firmware bug, or that 2.6.24-rc is hosed. The volume keys do NOT go through thinkpad-acpi on the T61 with the latest BIOS and EC firmware, unless it is in NVRAM poll mode (which is likely to cause all sort of weirdness, as the keys will be reported twice since the BIOS/EC is sending them over the normal keyboard controller). -- "One disk to rule them all, One disk to find them.
