--- Comment #2 from William D. Pool <rotae...@gmail.com> --- Performing some debugging I have verified the following. With and without PowerD enabled the below behavior is consistent. I'm able to perform ICMP pings between host-a (FreeBSD FW16) and host-b (macbook pro OSX) bi-directional without obtaining any ath0 device timeouts on the FreeBSD host-a. This has been performed up to 2hrs without issues on various tests. However, soon as any TCP based service to or from the FreeBSD (host-a) machine the whole stack locks up and I obtain ICMP timeouts on those same ICMP pings. The most obvious TCP test was SSH. Once you try to SSH to / from the FreeBSD host-a machine the whole network stack locks-up/freezes. Soon as I kill whatever the TCP process (SSH for example) is on the FreeBSD host-a or to the FreeBSD host-a within 45-60seconds the ICMP pings proceed and there's no device timeouts. Something is causing the device to lock/freeze on TCP connections. I will try to obtain some kernel debugging info -- You are receiving this mail because: You are the assignee for the bug.
