Hi, Sorry if my question is off-topic for this list. I have a computer that experienced a kernel failure while a was far away and nobody could reboot it. So I thought it would be nice to have a watchdog. Unfortunately, to the best of my knowledge, it has no hardware watchdog, so I thought I should add one. Hence, do you have suggestions for I²C-, serial- or USB-connected watchdog add-ons? It should of course be compatible with linux. I found http://www.berkprod.com/Product_Web_Pages/usb_v1_pc_watchdog.aspx but I think it is a little too expensive. If no such thing exists, I might consider designing my own (open hardware) I²C- or USB-connected watchdog add-on, using a cheap MCU. But then I would welcome opinions on what the interface between the host and watchdog should look like. Cheers, -- Nicolas Boullis
