Pandaboard reboot issue

Hello.

I am working on omap4 custom board with the kitkat android. what i see is the reboot command is very inconsistent. 7 out of 10 times it does not work. We see that the pulse to the PMIC during reboot is going. however, it does not reboot.

Not sure if it is hanging at the xloader level or at the kernel level. Tried the xloader patch which is for 4430. however, seeing the same issue.

Has anyone seen this issue?

Thanks for your help and assistance.
