How to avoid Reboot delay in 4.4 Image

Hi,

I have an doubt in the custom kernel image 4.4 built from RobertCNelson and running in SD card. The ‘reboot’ command takes more than 6 minutes for the BeagleBone black to reboot. Has anyone seen this issue? How could I avoid this 6 minutes delay.

Thanks,
