Hi,

I have an old Compaq Armada 1592DT. The thing goes automagically into
suspend mode after being forgotten for a while. And there is this button
to wake it up (the blue one, above the keyboard).

Last time i tried to wake it up it produced the attached oops.
"Unknown key"s are probable the blue button.
After printing out the oops, the system went back into suspend.
