Hi, I use OpenBSD 5.6 GENERIC.MP (amd64) on a Thinkpad T440. I often use the suspend state and i've noticed that after each suspend, in the next 5 minutes after resuming, my network interface (em0) looses connection during about 1 or 2 minutes and then reconnect and so on, many times... As you can see, the dmesg shows many em0 watchdog timeouts. I've tried to suspend when the laptop is on the dock and without it, but the problem is the same. No problem with the NIC when i don't suspend.
I use apmd_flags="-C" in /etc/rc.conf.local Any idea ? Thanks for your help.
