The watchdog is working in all the internal testing that we've done, if there's some corner case here then I need more info to reproduce it. I'm confused about what's what, which machine is your desktop and what is the 'other' system? For instance, we had a loud complaint about the watchdog here a while back, and it turned out the user had increased the system HZ value to something really high... I've yet to see something that indicates the code is broken. If it involves Windows then it goes outside the parameters of my testing so who knows :) Jack On Tue, Aug 3, 2010 at 7:02 PM, Scott Johnson <scottj75074@yahoo.com> wrote: > Under 8.0-RELEASE I would get warnings from em(4) in /var/log/messages > about > > "watchdog timeouts" on em0 whenever my desktop PC connected to em0 was > powered > off.
