Hi,

after upgrading to 4.3-rc gta04 board during boot print following warning:

(3f77f702389b7fbc955ec95721ce3861e40697fc) warning is gone and rootfs

but we see strange errors during booting like:

which are repeated until we get prompt (after 1-2 minutes).

Any idea what could cause this problems? On 4.2 it works fine. Many thanks.

BR,

marek

as simple and primitive as possible
