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?
