[BUG] linux laptop keyboard problem since 2.5.74

[BUG] linux laptop keyboard problem since 2.5.74

[Warren Turkal]

Sorry for the crosspost, but I didn't get a response originally from the 
acpi-devel list. Also, I am not subscribed to either list. Please CC me on 
replies that should go to me.

Something got merged between 2.5.73 and 74 that has messed with my system ever 
since. Some of the keys that are activated with Fn combinations are messed up.

Some of these combinations involve turning on external monitor output and 
showing battery status.

I suspect ACPI as that was the culprit last time when I could not use the Fn 
combinations at all. I compiled my kernel with acpi as modules and the 
problems happens even when not loading the modules for acpi. I also tried 
booting with acpi=off and that did not seem to change anything.

Like I said, 2.5.73 was fine and didn't lock like 2.5.74 to 2.6.0-test1 do. So 
the bug was somewhere in that revision.

I have a Gateway 600 series laptop with 256mb ram and 1.9Ghz P4. Does anyone 
know where I should start investigating for more info.

Thanks, Warren Turkal

I don't think it's ACPI to blame. The ACPI-related changesets applied
between 2.5.73 and 2.5.74 don't look like the culprit. Also, since it
continues to happen when acpi=off that also points away from ACPI.

I have other reports of things breaking in the same timeframe so I think
it's fair to say that something has regressed...somewhere.
