 Hi,

I am trying to trace the IRQ number of my keyboard and mouse from /proc/interrupts.

The contents of my /proc/interrupts is

[root@localhost ~]# cat /proc/interrupts
           CPU0
  0:     547208    IO-APIC-edge  timer
  7:          0    IO-APIC-edge  parport0
  8:         10    IO-APIC-edge  rtc
  9:          0   IO-APIC-level  acpi
 12:        102    IO-APIC-edge  i8042
 14:      18447    IO-APIC-edge  ide0
169:       6477   IO-APIC-level  eth0, i915@pci:0000:00:02.0
185:      14483   IO-APIC-level  libata
193:       6420   IO-APIC-level  Intel ICH6, uhci_hcd:usb5
201:          3   IO-APIC-level  ehci_hcd:usb1, uhci_hcd:usb2
209:      40821   IO-APIC-level  uhci_hcd:usb3
217:          0   IO-APIC-level  uhci_hcd:usb4
NMI:          0
LOC:     547164
ERR:          0
MIS:          0
[root@localhost ~]#  

I am not able to find out which IRQ above corresponds to the keyboard and mouse. I tried disable_irq() for each one of the IRQs mentioned above, but nothing disabled the mouse or keyboard. But disable_irq(169) disabled eth0 as expected.

Can anybody please help ?

Thanks,
Rajaram.
