Description Ruben Jenster 2006-10-07 10:09:46 UTC

Most recent kernel where this bug did not occur: 2.6.17.13
Distribution: Gentoo
Hardware Environment:Thinkpad T41p 2373-GHG

Problem Description:
I happens rareley but sometimes my laptop doesn't resume from S3.
I can press either LID or SLPB or PWRF but nothing happens -
the system just remains in S3 state.

If I manually disable SLPB/LID button through '/proc/acpi/wakeup',
it's still possible to resume the system by pressing the power button.


messages when issueing 'echo LID > /proc/acpi/wakeup':

#begin
ACPI: 'SLPB' and 'LID' have the same GPE, can't disable/enable one seperately
ACPI: 'UART' and 'LID' have the same GPE, can't disable/enable one seperately
#end

A conflicting module may be 'ibm-acpi' that is loaded with 'experimental=1 
hotkey=enable,0xffff'.


Regards,
Ruben

I'm sorry, but the following information was wrong. 
'Most recent kernel where this bug did not occur: 2.6.17.13'

Is this still a problem in linux-2.6.22.stable or later?

I'm typing this on a t41, and it works for me...

This is not any longer a problem with newer (2.6.22.x) kernel versions.
