The problem occured with both a USB mouse and a PS/2 mouse.  eth0 is on irq10.  The usb-ohci driver is also on irq10 but the PS/2 mouse, when it's plugged in, is on irq12.

I'm also having another problem with the nvnet driver.  Occasionally, when I initiaite network activity (click on a hyperlink, enter a URL, etc.), I get a complete lock-up.  Keyboard goes dead (no response from capslock lights even) and mouse goes dead.  Fortunately, I've found that I can bring the system back to life by unplugging the network cable and then plugging it back in.
This is all very odd, I'm going to disable the integrated nic and install a Linksys nic and see if the lockups continue.
