>Description:
On startup, sometimes it gets stuck, with lines of text saying "interrupt storm error". (The actual wording is: "interrupt storm detected on "irq17:"; throttling interrupt source".)

It appears to be caused by the USB mouse.  I know that the USB mouse works properly and there are no hardware faults of any kind.
>How-To-Repeat:
Use a USB mouse and sometimes (not always) the bootup will freeze and only output lines of the error message.
>Fix:
