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. This was fine, except for the annoying warnings. Under 8.1-RELEASE I no longer get the warnings, and any time my desktop is powered off, when I turn it back on, it has no connectivity. The interface is dead until I log into the console and run: # ifconfig em0 down up The em(4) driver has changed a lot since 8.0-RELEASE. It seems this watchdog timeout is no longer working. The board is a Supermicro X7SPA-H with Intel 82574L GbE. Any ideas for debugging?
