All have the watchdog on. I think it's a ACPI interaction problem with watchdog, so depending on your= =20 motherborads ACPI implementation you see the error or not, but I'm complete= ly=20 new to SW_WATCHDOG so I can't tell much when and why these irq statistics a= re=20 generated. Maybe Sean Kelly can tell us how SW_WATCHDOG interacts with ACPI, since I=20 think the problem occurs when the kernel disables ACPI, right?
