We have a problem with one of our products. In below zero temperatures, once Windows XP is loaded, the hardware interrupts are consuming 50% CPU. This can be seen in Sysinternals Process Explorer.
Does anyone know of a program that will give even greater detail of what is happening? Is 'resetting' IRQs possible through for example a WMI script? A software solution would be great as we have over 200 units out with customers. We are also looking into a BIOS fix, though even if this will solve the problem, flashing the BIOS is a more complicated procedure for our customers.
Any input is welcome!
