Tom, Try again, Ubiquity AR71xx based stuff (all the M series) supports a hardware watchdog fine.
from dmesg via OpenWRT. Atheros AR71xx hardware watchdog driver version 0.1.0 Regards Michael Baird > A hardware watchdog timer, typically, watches only one thing - is the > software and/or CPU still alive? If a software pinger fails to reset a > hardware counter or timer every few seconds or so, the timer reaches the end > of its count and resets the motherboard. It is a failsafe if everything else > goes wrong - something that happens more often than one would like when > you're using developmental drivers. Software watchdogs are a poor substitute > for obvious reasons - if the software or CPU is completely hung, the > software watchdog won't work either! > > Tom S. > > ----- Original Message ----- > From: "Mark Stephenson" <m...@countryconnections.net> > To: "WISPA General List" <wireless@wispa.org> > Sent: Sunday, December 20, 2009 4:12 AM > Subject: Re: [WISPA] Ubiquiti ready for prime time? > > > >> Tom, >> >> Do you happen to know what a hardware watchdog timer watches?
