Even though it's one timer > implementing 4, it's expensive to use it as a watchdog. It's not a watchdog, the timer continually fires.

The driver timer in question runs every 2 seconds to write this heartbeat message to the chip. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
