Hi Mike, Sorry to hear you are having problems like this. Can you please get the output from 'cat /proc/interrupts' both before the problem happens and then again once it does happen.
Does the system have the latest BIOS on it? Sometimes problems like this shows up when there are BIOS issues. Please also supply information on the system this is happening on. Is this happing only on one system or multiple systems? Thanks.
