[ltp] T22 halt including powering off - ACPI or APM

[michelh]

Sorry to catch up on a thread long after it has been active.

I was curious about this. Do the volume buttons generate an ACPI event on
your thinkpad ?
on My T22 the only key/button that generate an ACPI event are
	 	 Fn-F3 -> ibm/hotkey HKEY 00000080 00001003
		 Fn-F4 -> ibm/hotkey HKEY 00000080 00001004
		 Fn-F12 -> ibm/hotkey HKEY 00000080 0000100c
provided:
1) module ibm_acpi is loaded
2) hotkey are enabled (echo enable > /proc/acpi/ibm/hotkey)
Remark by the way: the mask (aka echo 0xffff > /proc/acpi/ibm/hotkey --
enable all possible hot keys) as mentionned in ibm-acpi-0.11/README) has no
effect (echo 0xffff > .../hotkey does not change behaviour)

I had the same problem boot argument ec=0 seems to solve it
 See   acpi suspend to ram on FC5 and IBM thinkpad T22

Sorry about asking stupid questions what do you mean by OSD.
Is it the sound buttons (  <volume down> <volume up> <volume mute> ?) or On
Screen Display of the voume like in   TPB .

Many thanks
