Hi, We have a patch with fix for an issue raised by Microsoft : "FreeBSD 11.2 - Kernel panic when flapping network interfaces on and off" . The issue was observed when the customer was trying to flap interface on and off in a loop more than 20 times. After investigation, it was found that panic occurred due to a thread sleeping while holding a mutex after a calling function pause().
I have attached the patch that has to be submitted upstream. Please let me know if I need to add someone for reviewing it. Also, please let me know if you have any questions. Thank you, Anand A. Khoje
