Hi all,
I've compiled a build with updated meta-arago (master) and meta-ti (daisy).
My board is a AM335x Starter Kit rev 1.2B with AM3359 CPU.
The kernel compiled is linux-ti-staging 3.14.17 with no personal changes.

The boot process shows 2 problems:
- Division by zero in kernel while probing davinci mdio
- the process stops "Waiting for root device /dev/mmcblk0p2..."

Attached you can find the full boot log.

Are these known problems or may be related to something known?
If yes, is there any available workaround?

I also tried latest TI_LinuxSDK_07.00.00.00 (march 2014) available on TI 
website.
Although is based on kernel 3.12, the boot process looks ok and Matrix 
start correctly.

Thanks
Regards
Pierluigi
