Hello, I upgraded 7.3 to 8.1 and am receiving "interrupt storm detected on "irq9:"; throttling interrupt source" errors.

Code: 
vmstat -i
interrupt                          total       rate
irq1: atkbd0                           2          0

From what I have read, it looks like a hardware problem with my raid controller, but I am not sure. could anyone confirm or let me know where else to look?

Thanks in advance,

Eric

Why do you say that? Your [cmd=""]vmstat[/cmd] output shows that your 3Ware controller is on irq24. irq9 is the ACPI device. You may find the "Using and Debugging FreeBSD ACPI" section of the Handbook useful.

You could also use the boot menu option "2. Boot FreeBSD with ACPI disabled" to see if that helps. Note that this will disable most power management features until you reboot without this option.
