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 
away.

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.
