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

[Matthew Boehm]

OK. Perhaps I was not clear. Please read my original post again:

I did not say "90% usage" I said "90% idle". Meaning I have a constant CPU
usage of 10%.

This 10% measurement comes from the "hardware interrupt" (hi) from within
"top":

Cpu(s):  3.8% us,  2.1% sy,  0.0% ni, 85.5% id,  0.2% wa,  8.0% hi,  0.4% si


Even when all other percentages are at 0%, hi remains around 10%. How can I
figure out what is causing all these interrupts?
