I haven't followed everything in your scenario, but:

1. Does tcpdump on npflog0 report any packets being dropped?

2. Does tcpdump on any of the interfaces involved show where the
   packet is getting dropped?

3. What have you done to try to reproduce the problem on a simplified
   configuration to narrow it down?  E.g., no bridge, no lagg, &c.
   Can you find the part of the configuration where it ceases to work?

4. Do you have dmesg from the previous boot when this happens, or
   serial console?

5. Can you use crash(8) to find the kernel stack trace of the process
   that's eating CPU?
