Nick,  I applied your patch = into linux kernel 4.13, rebuild it, installed it, then had a test, still ca= n not boot OS. System hung here, the same as before. Would you please have= a look? The system is going d= own NOW! Sent SIGTERM to all processes
Sent SIGKILL to all processes[  104.755810] kexec=5Fcore: Starting new kernel
