[Asterisk-Users] OT: Hardware Interrupts; Who is it?

[Matthew Boehm]

I've been trying to diagnose why my server has a constant idle time of 90%
even when nothing is running.

After finally discovering what "hi" means in 'top' (it means hardware
interrupts) I find that this percentage always averages around 7-10%.

How can I find out what is causing this constant load of interrupts?

I have a Dell 1850 3.0Ghz with on board RAID and 2GB RAM.

Anyone else experiencing this?
