Comment(by vnevoa):
Oops, sorry, I only looked at the /proc/interrupts output.
Now I'm looking at the kernel messages.
When I press the AUX button, I get only 1 message:
"IRQ press:0"
When I release the button, I get 2 messages:
"IRQ press:0"
"IRQ press:1"
Now I see the Power button also behaves strangely, I think.
I press Power, and I get 3 kernel messages:
"INT1=0x80 INT2=0x02 INT3=0x00 INT4=0x00 INT5=0x00"
"INT1=0x00 INT2=0x00 INT3=0x00 INT4=0x00 INT5=0x00"
"INT1=0x00 INT2=0x00 INT3=0x00 INT4=0x00 INT5=0x00"
I release it, and I get another 3:
"INT1=0x00 INT2=0x01 INT3=0x00 INT4=0x00 INT5=0x00"
"INT1=0x00 INT2=0x00 INT3=0x00 INT4=0x00 INT5=0x00"
"INT1=0x80 INT2=0x00 INT3=0x00 INT4=0x00 INT5=0x00"
Is this supposed to happen?
