Hi,

I am trying to boot kernel 4.4 on Jacinto-6 EVM board, I am facing error
from xen. Please find attached log to find errors.

The kernel is stuck at
[    6.881378] Waiting for root device /dev/mmcblk0p2...

Is it due to i2c related errors in boot log as mentioned below?
[    0.831911] palmas 0-0058: IRQ missing: skipping irq request

Can anyone provide the solution to these problems?

Thanks,
