I have not been able to reproduce the problem with other interfaces. This problem occurs whether APIC is turned on or not. >How-To-Repeat: compile kernel: +options IPSEC +options IPSEC_ESP +options IPSEC_DEBUG OR add 'debug.mpsafenet="0"' to /boot/loader.conf kldload crypto generate network traffic: nttcp -D -l 65535 -T 10.129.0.2 (repeat until hang/watchdog timeout) >Fix: The watchdog timeout will usually reset the interface and allow operation after a few seconds. In the case the watchdog timeout does not kick in, bringing the interface down then up will have the same effect. >Release-Note: >Audit-Trail: >Unformatted:
