Dear All,

I am working with processor SDK with Customized board designed with AM5728. While booting it is getting crashed with the following. Can any one help on this. we are working on this kind of issues since long time.

Are you getting this panic every time or some times ?
If you reset the board the panic is not coming in next time ?

Can you please remove the udev service in filesystem ?

I have a similar problem, but it occurs completely randomly. I can boot the board many times without having the error, but sometimes it appears just after booting while running udev. The error is:
