Description Luming Yu 2003-10-27 03:58:50 UTC
RH 9 + base kernel 2.6.0-test7,test8

Hardware Environment:
IBM Thinkpad T21

Problem Description:
If you press fn+F4 , or other function keys, there should be only 1 ACPI
interrupt generated rather than 2.

Steps to reproduce:
a). boot up kernel with full ACPI features.
b). cat /proc/interrupts
11:      6        XT-PIC   acpi
c). press Fn+F4(or other function keys)
d). cat /proc/interrups
11:      8        XT-PIC   acpi

Comment 2 Andy Grover 2003-10-30 10:03:03 UTC
or can you just call acpi_clear_gpe from ec.c?
Comment 3 Robert Moore 2004-09-22 15:21:54 UTC
Please explain how this patch fixes the problem.

Also -- with the major GPE changes in mid-2004, this problem *may* have gone 
Comment 4 Len Brown 2004-11-16 23:49:22 UTC
please verify that this is still a problem in 2.6.9
Comment 5 Luming Yu 2004-12-01 01:45:05 UTC
I don't have access to T21 now. 
But I have T42. With 2.6.10-rc2, each FN+F4 cause 4 increment. 
Comment 6 Robert Moore 2005-03-09 12:25:39 UTC
Is this still a problem?
Comment 7 Luming Yu 2005-04-27 00:55:13 UTC
The assumption should be wrong, because it depends on implementation.
