Hi Sudeep,

Thanks for the pointer. I tried your patch from [1] and it fixes the kexec issue on my setup.

I also tried limiting the shutdown patch to just RXTX_UNMAP, but that is not sufficient here.
The next kernel can still fail notificaion setup with:

ARM FF-A: Notification bitmap create error -13

So I agree that using the normal FF-A cleanup patch from shutdown looks like the right approach,
since it tears down the notification bitmap state as well as unmapping the Rx/Tx buffers.

Are you planning to submit that change to resolve this issue?

Thanks,
Carol
