Hi, I just loaded & updated to the latest RELENG_5_3 branch a dual proc
HP Proliant DL145. I have 2 odd messages that have me a bit concerned.
The first has to do with irq throttling in /var/log/messages:
Mar 17 17:14:41 fbsd2 kernel: Interrupt storm detected on "irq19: ohci0
ohci1"; throttling interrupt source
And the second is something about throttling the CPU (in *bold* for easy
location) upon boot-up:

My main question is if these 2 messages are something I need to worry
about and/or fix.
