Its 'cat /proc/interrupts'. Thanks, Hirakendu.

I did that but nothing changed :/ Even without any governor my CPU would go for 80000 wakeups/s. > Btw, some time back at gentoo forums, someone (who also had this high > wakeups issue) had suggested that the userspace cpufreq governor isn't > that good (btw, his problem also mysteriously disappeared for good, > after some arbirtary kernel config changes).

You mentioned something about shared IRQs. Is there a way to test if some things are sharing the same IRQ? This is my last hope.
